Question: Who composed Depeche Mode's first gold-certified single in the US?
Context: The Best of Depeche Mode Volume 1 is a greatest hits album by the English electronic band Depeche Mode, released on 8 November 2006 by Mute Records.  The album consists of select Depeche Mode singles from their then-25-year career, as well as the previously unreleased track "Martyr"—recorded during the "Playing the Angel" sessions—which was released as a single in late October 2006. "Shake the Disease" is Depeche Mode's thirteenth UK single recorded at Hansa Mischraum in Berlin (released on 29 April 1985), and was one of two new songs released on the compilations "The Singles 81→85" (UK) / "Catching Up with Depeche Mode" (US) the same year, along with subsequent single "It's Called a Heart". "Policy of Truth" is a song by English electronic band Depeche Mode, released in May 1990 as the third single from their seventh studio album "Violator" (1990).  Although the song was less successful than the first two singles before, it is the only Depeche Mode single to chart higher on the US "Billboard" Hot 100 chart (#15) than on the UK Singles Chart (#16), as well as peaking at number two on the "Billboard" Dance Club Songs chart.  It also became the band's second chart-topper on the "Billboard" Modern Rock Tracks chart. Martin Lee Gore (born 23 July 1961) is an English singer-songwriter, guitarist, keyboardist, producer, remixer, and DJ.  He is one of the founding members of the band Depeche Mode, and also has written the majority of their songs.  His work now spans over four decades.  Gore's best-known compositions include hits such as "Personal Jesus", "Enjoy the Silence", "Stripped", "It's No Good", "In Your Room", "Strangelove", "I Feel You", "People Are People", "Precious", "A Question of Time", "Policy of Truth", "Everything Counts", "Behind the Wheel", "Shake the Disease", "Never Let Me Down Again", and many more. "Personal Jesus" is a song by the English electronic band Depeche Mode, released on 28 August 1989 as the lead single from their seventh album, "Violator" (1990).  The single reached No. 13 on the UK Singles Chart and No. 28 on the "Billboard" Hot 100.  The song was the first single to make the US Top 40 for the band since their 1984 single "People Are People" and was their first gold-certified single in the US (quickly followed by the band's subsequent single, "Enjoy the Silence"). "John the Revelator"/"Lilian" is the second double A-side single by Depeche Mode and their forty-fourth single overall, released on 5 June 2006.  Both songs are featured on Depeche Mode's 2005 album, "Playing the Angel" and serve as the fourth single from the album (see 2006 in British music).  The single became another UK Top 20 hit for the band, reaching number 18. "See You" is the fourth UK single by Depeche Mode recorded at Blackwing Studios, and the first Depeche Mode single written by Martin Gore.  The single was released on 29 January 1982 and was later included on the band's second album "A Broken Frame".  The single launched a small world tour, with extra band member Alan Wilder, although he did not contribute to the song or the album.  There are three versions of "See You"—the 7" single version (3:55), the album version (4:34), and an extended 12" version with a longer intro (4:50).  The "Extended Version" and the "Album Version" are almost the same.  The "Album Version" fades out about 20 second before the 12" remix does. "Fragile Tension"/"Hole to Feed" is Depeche Mode's third single from their studio album, "Sounds of the Universe", their 48th UK single overall, and their third double A-side single, following "Blasphemous Rumours / Somebody" and "John the Revelator / Lilian".  "Hole to Feed" is the second Depeche Mode single written by Dave Gahan along with co-writers Christian Eigner and Andrew Phillpott, succeeding the first being "Suffer Well", from their previous album "Playing The Angel".  Gahan told "The Guardian" that "Hole to Feed" is, "a very cynical song about wanting to fill a gaping hole but not knowing what to fill it with.  About sometimes the idea of having a hole to feed all being a figment of my imagination when I'm actually fine." "Martyr" is the 45th UK single by Depeche Mode.  It was released as a non-album single intended to promote the new compilation, "The Best Of, Volume 1", that was released on 13 November 2006.  The single was released on 30 October 2006 in three formats: CD single, CD maxi and DVD single.  There was also a limited edition double-12" single (L12BONG39) featuring four remixes of previous Depeche Mode tracks. Depeche Mode are an English electronic band that formed in Basildon, Essex in 1980.  The group consists of founders Dave Gahan (lead vocals), Martin Gore (guitar, keyboards, vocals), and Andy Fletcher (keyboards, bass guitar).  Depeche Mode released their debut album "Speak & Spell" in 1981, bringing the band onto the British new wave scene.  Original band member Vince Clarke (keyboards, guitar), left the band after the release of the album, leaving the band as a trio to record "A Broken Frame", released the following year.  Gore took over the lead songwriting duties and, later in 1982, Alan Wilder (keyboards, drums, bass guitar) officially joined the band to fill Clarke's spot, establishing a line up that would continue for the next 13 years.  Depeche Mode have been a trio again since 1995, when Wilder left.
