Question: Are both musicians Marilyn Manson and Ville Valo also a song-writer?
Context: Ville Hermanni Valo (born 22 November 1976) is a Finnish singer-songwriter and multi-instrumentalist, best known as the lead vocalist and main songwriter of the Finnish gothic rock band HIM.  Influenced by the likes of Black Sabbath and Type O Negative, Valo began his career playing bass and drums in various bands around Helsinki, before forming HIM in 1991.  The band would go on to become one of the most commercially successful Finnish bands of all time, and the first to receive a gold record in the United States.  Valo is also credited as the creator of the heartagram, the trademarked symbol of HIM. Brian Hugh Warner (born January 5, 1969), known professionally as Marilyn Manson, is an American singer, songwriter, musician, composer, actor, painter, author and former music journalist.  He is known for his controversial stage personality and image as the lead singer of the band Marilyn Manson, which he co-founded with guitarist Daisy Berkowitz and of which he remains the only constant member.  His stage name was formed by combining and juxtaposing the names of two American pop cultural icons: actress Marilyn Monroe and cult leader Charles Manson. Screamworks: Love in Theory and Practice, Chapters 1−13 is the seventh studio album by Finnish gothic rock band HIM.  Released on 8 February 2010, the album was recorded at The Lair Studios and NRG Studios in Los Angeles, California, with producer Matt Squire, who had previously worked with The Used and Panic!  at the Disco among others.  "Screamworks" was HIM's first album that vocalist Ville Valo worked on completely sober following his time in rehab, which resulted in the band rehearsing more than ever before.  Valo had set out to prove himself following his new-found sobriety, but the excessive rehearsing eventually wore some of the band out.  Musically "Screamworks" featured a more accessible and straightforward sound than its predecessor, with influences from the music of the 1980s.  Much of the album's material was inspired by a relationship of Valo's with an undisclosed partner, who served as his muse. Jesse Valo (born on July 26 1983) is a professional Muay Thai kickboxer from Helsinki, Finland.  He is the younger brother of the singer Ville Valo, front man of the Finnish band HIM. Marilyn Manson is an American rock band formed by singer Marilyn Manson and guitarist Daisy Berkowitz in Fort Lauderdale, Florida, in 1989.  Originally named Marilyn Manson & the Spooky Kids, they gained a local cult following in South Florida in the early 1990s with their theatrical live performances.  In 1993, they were the first act signed to Trent Reznor's Nothing Records label.  Until 1996, the name of each member was created by combining the first name of an iconic female sex symbol and the last name of an iconic serial killer, for example Marilyn Monroe and Charles Manson.  Their lineup has changed between many of their album releases; the current members of Marilyn Manson are the eponymous lead singer (the only remaining original member), bassist Twiggy Ramirez, guitarists Paul Wiley and Tyler Bates, and drummer Gil Sharone. HIM is a Finnish gothic rock band from Helsinki.  Formed in 1991 by vocalist Ville Valo and bassist Mikko "Mige" Paananen under the name His Infernal Majesty, the band broke-up in 1993 however, before being reformed in 1995 by Valo and guitarist Mikko "Linde" Lindström.  After being rejoined by Mige, as well new additions keyboardist Antto Melasniemi and drummer Juhana "Pätkä" Rantala, the band, now called HIM, released their debut album "Greatest Lovesongs Vol.  666" in 1997.

Its first single, "Join Me in Death", also charted at number one in Finland and Germany, eventually going platinum and gold respectively.  Following the addition of Janne "Burton" Puurtinen on keyboards, HIM released "Deep Shadows and Brilliant Highlights" and "Love Metal" in 2001 and 2003 respectively.  Both cracked the top ten in several countries, and allowed the band to tour the United Kingdom and the United States for the first time. "My Girlfriend" is a song by the Christian rock band Relient K, released on their self-titled first album.  The song originally appeared as "Marilyn Manson Ate My Girlfriend" on the band's demo album, "All Work and No Play".  The song is about Marilyn Manson eating Matt Thiessen's girlfriend.  Thiessen wrote this song when he was 15 years old.  Thiessen has said that he wrote it because of a female friend, who lived eight hours away in Pennsylvania, who he would talk to about many things including spiritual matters such as where God was taking them in the future.  His friend would later turn from Christian music to Nine Inch Nails and Marilyn Manson.  In an interview with CCM Magazine Thiessen stated "through this she changed her lifestyle [and] what she believed in."  His friend would later be expelled from school and would be kicked out of her house and sent to a youth detention center.  Thiessen would later state "She felt that Christianity was stupid and just this big hypocrisy.  Being young and impressionable, I just wrote this little, stupid song, but that was the way I dealt with it—writing this song about how she got so consumed by Marilyn Manson." Finnish gothic rock band HIM have released eight studio albums, one live album, eight compilation albums, one EP, twenty-seven singles, three video albums, and twenty-nine music videos.

"Bittersweet" is a single by the cello rock band Apocalyptica in collaboration with Ville Valo (of HIM) and Lauri Ylönen (of The Rasmus).  The music is by Apocalyptica, the lyrics by Ville Valo and the vocals by Ville Valo and Lauri Ylönen.  The song is written for four cellos (quartet) and voice, but there are versions for just the cello quartet.  The lyrics are about a love triangle, in which a woman loves a man, who does not love her back, and another man which is in love with the woman, while she does not love him back. Venus Doom is the sixth studio album by Finnish gothic rock band HIM.  Released on 14 September 2007, the album was recorded at Finnvox Studios in Helsinki, Finland, with producers Hiili Hiilesmaa and Tim Palmer, both whom had collaborated with the band on various occasions.  The making-of "Venus Doom" was plagued with personal problems vocalist Ville Valo was facing at the time.  Among other things, his alcohol abuse had worsened to the point that he suffered a nervous breakdown during the recording process, after which he was admitted to the Promises Rehabilitation Clinic in Malibu by HIM's manager Seppo Vesterinen.  Musically the album has been described as HIM's heaviest and darkest album to date, with influences from bands, such as My Dying Bride, Anathema and Paradise Lost.  Much of the album's lyrical themes and heaviness were inspired by Valo's personal difficulties, including his break-up with fiance Jonna Nygrén.
