Hydrogen

Hydrogen's Only In My Head music video.

**Hydrogen** was a Snowiss girl group formed by SNOW Entertainment in 2007, comprising of Yumi Tanaka, Akira Minamoto, Fruita Starbasher, Hana Watanabe and Ryuna Kisaragi.

## Events

### Pre-debut

Hydrogen was originally meant to be a seven-member group, however, this was scrapped off.

The first Hydrogen member to enter a training contract under SNOW-E was Akira, who auditioned in early 2002 during the first SNOW Entertainment National Auditions in Centralia, Snowlands. Among the 200 participants for the girls, Akira came in sixth in best execution and eighth in best singer categories, which led her to enter the agency in October 2002.

Fruita and Hana were the second and third members, respectively, to enter SNOW-E. Both auditioned for the second annual SNOW Entertainment National Auditions held once again in Centralia, Snowlands. Fruita placed seventh in best execution, third in best singer and first in best rapper, while Hana placed fifth in best execution, fourth in best rapper and third in best dancer categories, landing both a contract with the agency in February 2003.

Ryuna entered SNOW-E after auditioning in the third annual SENA held in Awgen, Snowlands. She placed thirteenth on best execution, which would have not landed her into the agency if it weren't for her fifth best singer and first best dancer rankings. She joined the company on August 2004.

Yumi was the last member to enter the agency on the fourth SENA held in Osaperave, Snowlands. She marked first best execution and first best singer awards, as well as the third best dancer. She joined the company immediately after the audition, August 2005.

In December 2006, SNOW Entertainment announced the formation of a five-member girl group, which would have a unique but coordinated overall concept and would also debut with a single. Ryuna was the first member to be announced, followed by Hana, Fruita, Akira and Yumi.

## Discography

Hydrogen have released five studio albums and ten extended plays. One reissue has been released. Also, they have forty-seven singles.

* **Pastel Night** is the debut extended play of Hydrogen, containing five songs, also the lead single **Sweet Delight**. It was released both digitally and physically in Snowlands on 11 January 2007. The EP sold 800 thousand physical copies nationwide, with 3.3 million digital sales recorded. Also, as of October 2017, the music video for Sweet Delight, re-released on 2010 characterized by its colorful filters and environment has reached 400 million views on Scite.
	+ Pastel Night was awarded Album of the Year at the 2007 Snowiss Music Awards. Sweet Delight was also nominated for Song of the Year, but sadly, didn't win.
	+ Sweet Delight landed Hydrogen their first ever commercial advertisement contracts with the Cooleeze Frozen Goods, an ice cream company.
	+ On the second week of their promotions with Sweet Delight, member Akira got a knee injury, forcing her to not attend a week's worth of performances, and also, leading to the group to change their choreography positions and leave Akira's part unsung.
	+ Pastel Night contains the songs Sweet Delight, Would You Like?, Comic Strip, Repair, and Whoosh.
		- Sweet Delight was written, arranged and produced by the SNOW duo, composed of Lucas Park and Jack Choi (under the name DIAMOND). Sweet Delight talks of an impossible dream that you would only achieve by believing you can. It has an energetic, 8-bit soundtrack theme, synchronized with fast beats and a medium-dominant bass.
		- Would You Like? was written, arranged and produced by Mayu Arisawa. Would You Like? talks of a desperate girl trying to confess to her crush by giving him gifts. The song is characterized by its upbeat rhythm, drums prevailing over the synths.
		- Comic Strip was written by Yumi Tanaka and Fruita Starbasher, also, arranged and produced by Mayu Arisawa. Comic Strip talks of an event in a girl's unbelievable to be true, something that she saw in a comic strip, something that would have never happened in an ordinary girl's life. It has yet another upbeat theme with a guitar providing its main instrument.
		- Repair was written by the SNOW duo and Sachira Yoiko, and is also arranged and produced by the SNOW duo. Repair talks of a heart in need of fixing because it doesn't have the one it loves. It is a ballad, characterized by its mellow piano rhythm and snare drums.
		- Whoosh was written by Hana Watanabe and Ryuna Kisaragi, and is arranged and produced by Mayu Arisawa. As the final track for the album, Whoosh has a moderate rhythm, with the usual synths and drums, talking of problems that should be gone like WHOOSH!
* **Number Two** is Hydrogen's second EP, containing five songs, with the lead singles **Burn** and **Boom Boom Bloom**. Burn was pre-released on 26 May 2007 and Boom Boom Bloom on 30 October 2007, with the actual album released on 1 January 2008, both physically and digitally. It sold 4 million copies nationwide, with 10.7 million digital copies recorded. As of October 2017, the music video for Burn, re-released on 2010 has been viewed 870 million times and Boom Boom Bloom, also re-released on 2010 has been viewed 1.8 billion times in Scite.
	+ Number Two was nominated for Album of the Year in the 2007 Snowiss Music Awards, unfortunately, a one-point difference from Pastel Night made it second place. However, the music video for Boom Boom Bloom won Best Music Video award.
	+ Burn's promotion period on music shows lasted for only a month, however, Boom Boom Bloom, from originally a month was extended to two due to popular demand.
	+ Number Two contains five songs: **Burn**, **Boom Boom Bloom**, **Don't You Dare Say Anything**, **Refrain** and **Let's Have A Blast**.
		- Burn was written, arranged and produced by the SNOW duo, particularly showcasing Hydrogen's much darker side. Characterized by electric guitars and dominant drums, the song talks of a love that could burn and hurt you if you left it behind, more of like a promise that shouldn't be broken.
		- Boom Boom Bloom, written, arranged and produced by the SNOW duo, has a brighter side and a cute but vibrant concept. Showcasing synths and comic sound effects, it tells of a girl who has finally told her crush what her intentions and feelings are, and although her crush acknowledged this, she doesn't know what to do next.
		- Don't You Dare Say Anything continues Hydrogen's darker side, the side that could burn. Written, produced and arranged by the SNOW duo, this is characterized by its unnerving piano work with bass drums accompanying it. It tells of a relationship where a girl feels really left out by a guy, so she challenged herself to be a more mature woman and let herself boss the other guy around, without having the guy say anything to contrast the girl's wishes.
		- Refrain is yet another unnerving song, this time with synths and an occasional trumpet, but with the usual bass drum accompanying it. Written by Yumi Tanaka and Sachira Yoiko, and arranged and produced by Mayu Arisawa, this song is mellow and more of a ballad. It continues the story from Don't You Dare Say Anything. This time, everything has changed and the guy is in the brink of leaving the girl, so she thinks of different ways to refrain the guy.
		- Let's Have A Blast!, written by Ryuna Kisaragi, arranged and produced by the SNOW duo, is an upbeat party song with the piano-trumpet-drums theme. Let's push aside any problems and let's just party all night, Ryuna would say.
* **Truth** is Hydrogen's first studio album, containing 13 songs, seven of which are lead singles and all of which are released prior to the album debut. It sold 8 million physical copies and 18.9 million digital copies nationwide, making it the most best-selling album of Hydrogen for the year. It was released 25 December 2008.
	+ Truth won Song of the Year in the 2008 Snowiss Music Awards, and the Metropolitan Craze music video as Music Video of the Year. Hydrogen also won two consecutive top-spots in the Album of the Year award, one is Truth and the other Number Two. This made them win Artist of the Year.
	+ The lead singles include **Truth**, **Ink and Paper**, **Let's Call It A Day**, **Unseen**, **Metropolitan Craze**, **Spring Ring**, and **Only In My Dreams**. All songs ranked in the newly-developed Musicstream Top 50 List, and also all of these ranking on the Top 10.
	+ Truth contains thirteen songs: **Truth, Ink and Paper, Let's Call It A Day, Unseen, Metropolitan Craze, Spring Ring, Only In My Dreams, Ultimately On Top, To the Max, Headphones, Calendar, Holiday Breeze and Good Night**.
		- Truth, written by the whole Hydrogen unit, and arranged and produced by the SNOW duo, was Hydrogen's first song to be placed as a lead single. Unlike the title, Truth talks pretty much about lies and gossip, to which the girls have refuted successfully. Truth starts slow, and rises slowly into a dramatic climax in the choruses with the orchestra theme.
			* *"Boom boom! Like that! Gonna punch you with the truth!"*
		- Ink and Paper pretty much showcases the group's desires and wishes, to become successful, to leave a legacy behind, and "write it with ink and paper". Written by Akira Minamoto and Hana Watanabe, this song is pretty light-hearted, with an electric piano as a main instrument and the bass and the snares pulling the beats.
			* *"Why don't we start by writing it with ink and paper?"*
		- Let's Call It A Day focuses more on optimism and positivity after a long day of hard work and problem solving, but then, "let's call it a day". Written by Ryuna Kisaragi, this song is again, light-hearted and energetic, with a flute and synths serving as main instruments.
			* *"No, it's stress, acne's gonna grow again! Oh no no, I don't wanna FACE it!"*
		- Unseen is a ballad, literally talking about being unseen and unnoticed, being a regular person, being someone who doesn't get much attention even though you try your best to get everything right. Written again by all Hydrogen members, and arranged and produced by the SNOW duo, this piece focuses more on the vocals and harmonies of the girls, with a soft piano to accompany in every second and every minute of the song.
			* *"Why...? What do you see...? Open your eyes and you'll see me..."*
		- Metropolitan Craze jumps from the sadness into an ultra-upbeat summer song, telling about a life in the city, a difficult life of choices, what to wear, what to eat, where to go, as well as all the positive air around you while you walk in the sidewalks. Written, arranged and produced by the SNOW duo, it contains a lot of synths and drums as well as an accordion.
			* *"Jumping and running and walking the streets, everything seems perfect to me~"*
* **After All** is Hydrogen's third EP released on 15 March 2009. It contains five songs, with the lead single **Harmony**, which is pre-released to the market after a leaking scandal. After All sold 2 million copies nationwide and 10 million digital downloads.
	+ After All contains the tracks **Harmony**, **No Pressure**, **Blind Optimist**, **Shades of Blue** and **Little Bit Longer**.
	+ After All was highly appraised for its lyric work and content, however, some critics suggested that the album was a little bit mellow and lacked energy and competency. However, the album still sold over two million copies.

* **After All: Part Two** is Hydrogen's first reissue of the After All release, released on 20 December 2009, serving as a holiday present to Hydrogen fans.

Bold Ladies received good reviews despite being released a day late after the SNOW Entertainment headquarters underwent a major fire three days prior to the scheduled release of the album.
	+ This was the only album to have all side-tracks to be released first before the lead singles. Also, due to SNOW Entertainment's previous beef with music chart companies in March 2016, all lead singles were entered late in the charts and not on the real-time day of release.
	+ This incident led Hydrogen's songs to be entered valid for the 2017 music awards shows, which counts songs released from the final half of last year to the whole 2017 itself.
	+ **Bold Ladies** includes lead singles **Bold Ladies**, **Life**, **Miracle Tree**, **Time Traveler**, **Good Things**, **Euphoria** and **Nostalgia** as well as supporting tracks **Anthem**, **Your Freedom**, **Girl Power, Redeem**, **Fight Off** and **Severe**.
