Farrokh "Freddie" Mercury (born Bulsara; 5 September 1946 – 24 November 1991) was a British singer, songwriter and record producer, known as the lead vocalist of the rock band Queen.
 He was known for his flamboyant stage persona and four-octave vocal range.
 Mercury wrote numerous hits for Queen, including "Bohemian Rhapsody", "Killer Queen", "Somebody to Love", "Don't Stop Me Now", "Crazy Little Thing Called Love", and "We Are the Champions".
 He led a solo career while performing with Queen, and occasionally served as a producer and guest musician for other artists.
The Freddie Mercury Album is a posthumous solo project with material from Queen frontman and vocalist Freddie Mercury released in 1992, to observe the anniversary of his death.
 The album is mainly made up of remixes from his past releases, as well as the original versions of "Barcelona", "Love Kills", "Exercises in Free Love", and "The Great Pretender".
 A week later, The Great Pretender, its US counterpart, was released.
"The Invisible Man" is a song by the British rock band Queen, written by drummer Roger Taylor but credited to Queen.
 The song is sung mostly by Freddie Mercury, with vocal contributions from Taylor.
 Originally released on the album "The Miracle", it was released as a single in 1989.
 Taylor claims that he got the inspiration to create the song while reading a book (possibly the book of the same name), and the bassline instantly came to his imagination.
 This song marks the only time in any of Queen's songs that all four band members names are mentioned in the lyrics.
 The first being Freddie Mercury, followed by John Deacon.
 Brian May's name is then said twice (just before his guitar solo starts), and while saying "Roger Taylor", the first "r" is rolled to emulate the drums at the end of the verse.
 Freddie Mercury's name is said by drummer Roger Taylor, and the other ones by the lead singer Freddie Mercury.
Babymetal (stylized as BABYMETAL) is a Japanese metal idol band.
 Their line-up consists of Suzuka Nakamoto as "Su-metal", Yui Mizuno as "Yuimetal", and Moa Kikuchi as "Moametal".
 The concept of the group is a fusion of the heavy metal and Japanese idol genres.
 The three teenage girls and their band are managed by the Amuse talent agency.
 Their vocals are backed by heavy metal instrumentation played by the Kami Band.
 Babymetal released their eponymous debut album in February 2014.
 Their second album "Metal Resistance" was released worldwide on  01, 2016 (2016--) .
"Too Much Love Will Kill You" is a song written by British guitarist Brian May of Queen, Frank Musker, and Elizabeth Lamers.
 The song reflected the breakdown of May's first marriage and attraction to his future wife, Anita Dobson.
 It was first recorded by Queen around 1988 or before, and was intended to be on the band's "The Miracle" album in 1989, but did not make the cut due to legal disputes following the band's decision that all songs on the album would be written by the group as opposed to individuals.
 After Freddie Mercury's death in 1991, May arranged a solo version, which he performed at the Freddie Mercury Tribute Concert in 1992, and subsequently included on his solo album "Back to the Light" that same year.
 Released as a single, it reached No. 5 on the UK Singles Chart.
 Because it was first played publicly at The Freddie Mercury Tribute Concert, a common misconception is that it was written as a tribute to Freddie Mercury, although it had actually been written several years before he died.
Lover of Life, Singer of Songs (with the subtitle "The Very Best of Freddie Mercury Solo") is a compilation album of Freddie Mercury's solo songs.
 It was released (except in the U.S.) on 4 September 2006, the day before Mercury's 60th Birthday.
 It was released on 21 November 2006 in the U.S, three days before the 15th anniversary of Mercury's death.
The Magic Tour was the biggest and final tour by the British rock band Queen with their lead singer Freddie Mercury and their bass guitarist John Deacon, which took place in 1986.
 The band would not tour again until 19 years later, when the Queen + Paul Rodgers Tour began in 2005, after the death of Freddie Mercury on 24 November 1991, and the retirement of John Deacon in 1997.
 The Magic Tour took in 26 dates around Europe's stadiums, in support of their then latest album "A Kind of Magic".
Freddie Mercury: The Great Pretender is an Emmy/Rose d'Or award winning 2012 feature-length documentary about Queen singer Freddie Mercury and his attempt to forge a solo career.

 It gained 3.5 million viewers when aired on BBC One in October 2012 and a further 1.2 million when shown on BBC Four.
Suzuka Nakamoto (中元 すず香 , Nakamoto Suzuka , born December 20, 1997) , known by her stage names Suzuka and Su-metal, is a Japanese idol.
 She is best known as the lead vocalist of three-piece kawaii metal band Babymetal.

The Freddie Mercury Tribute Concert for AIDS Awareness was a benefit concert held on Easter Monday, 20 April 1992 at Wembley Stadium in London, England for an audience of 72,000.
 The concert was produced for television by Ray Burdis and broadcast live on television and radio to 76 countries around the world, with an audience of up to one billion.
 The concert was a tribute to the life of Queen lead vocalist, Freddie Mercury, with proceeds going to AIDS research.
 The show marked bassist John Deacon's final full-length concert with Queen (save a short live appearance with Brian May, Roger Taylor and Elton John in 1997).
 The profits from the concert were used to launch The Mercury Phoenix Trust, an AIDS charity organisation.
