Question: Are both musicians Marilyn Manson and Ville Valo also a song-writer?

full_context: Document 1: Venus Doom: 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.
Document 2: List of Marilyn Manson band members: Throughout the band's history, Marilyn Manson has only had one consistent member, being Marilyn Manson himself. This is a timeline of all of the band members since their formation in 1989. Most, if not all, members of the band have contributed performances (either live or in-studio) on instruments other than their primary ones. For instance, Gacy has played theremin and calliope, Manson has played pan flute, harpsichord, keyboards, and guitar, and Berkowitz has been credited with bass guitar and drum machines. Keyboardists Madonna Wayne Gacy and Chris Vrenna have also performed additional percussion on-stage, and current touring keyboardist Spencer Rollins plays additional guitar live. Further details on these contributions can be found in the individual members' articles, and in the articles on the band's albums.

Document 4: Marilyn Manson (band): 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.

After being rejoined by Mige, as well new additions keyboardist Antto Melasniemi, rhythm guitarist Oki and drummer Juhana "Pätkä" Rantala, the band, now called HIM, signed to BMG, and released the EP "" in 1996.

Document 8: Love Metal: Love Metal is the fourth studio album by Finnish gothic rock band HIM. Released on 11 April 2003, HIM began recording demos for the album in spring 2002, after an exhausting touring cycle for their previous album, which nearly broke the band up. Excited and invigorated by the new material, HIM entered Finnvox Studios in September 2002 with producer Hiili Hiilesmaa, who had previously helmed the group's 1997 debut album. Musically "Love Metal" featured a more raw and organic sound, inspired by the band's early influences, which was also seen as a reaction to the difficulties they faced while recording their previous album. Vocalist Ville Valo has since described "Love Metal" as the album where HIM found their sound. "Love Metal" was also the band's first album to predominantly feature their logo, the heartagram, on the cover, while the album's title was coined in the mid-nineties as a description for HIM's musical genre.
Document 9: The Manson Family Album: The Manson Family Album is the first studio recording by American rock band Marilyn Manson. It is a precursor to the band's debut studio album, 1994's "Portrait of an American Family". It was produced by Roli Mosimann, and is composed of original takes and mixes of songs which would later be found on their debut. However, the band's eponymous vocalist was unhappy with Mosimann's production, claiming it was too "smoothed and polished", and poorly representative of the band's established sound. The majority of songs on "The Manson Family Album" were later re-recorded or remixed with Nine Inch Nails frontman Trent Reznor at the Record Plant in Los Angeles. The album's title is a double entendre; it also relates to the commune of cult leader Charles Manson.

In 1971 he was found guilty of first-degree murder and conspiracy to commit murder for the deaths of seven people – most notably of the actress Sharon Tate – all of which were carried out by members of the group at his instruction. Manson also received first-degree murder convictions for two other deaths. Manson was originally sentenced to death, but his sentence was commuted to life imprisonment when California invalidated the state's death penalty statute in 1972. He is currently serving multiple life sentences at California State Prison in Corcoran.
