Context: System of a Down is an American rock band formed by musicians of Armenian origin: vocalist Serj Tankian, guitarist Daron Malakian, bassist Shavo Odadjian, and drummer John Dolmayan in the mid-1990s.  They have released five studio albums, 16 singles, and 11 music videos. By the end of 1997, the group had signed to American Recordings, then distributed as Columbia Records.  The following year, they released their eponymous debut album, which peaked at #124 on the United States' "Billboard" 200 and #103 on the United Kingdom's UK Albums Chart; it was certified platinum two years later by the Recording Industry Association of America (RIAA), and gold by Canadian Recording Industry Association (CRIA).  Their eponymous debut album produced a single for the song "Sugar", which reached the top 30 on the "Billboard" mainstream rock songs and alternative songs charts.  Their follow-up album, "Toxicity" (2001), topped the US and Canadian charts, and also reached the top 10 in Australia, Finland, and New Zealand.  The album was certified triple platinum in its home country, and triple platinum in Australia by the Australian Recording Industry Association (ARIA), as well as double platinum by CRIA in Canada.  "Toxicity" produced singles for the title track, "Chop Suey! ", and "Aerials".  The last of these peaked at number one on the "Billboard" Mainstream Rock Songs and Alternative Songs charts. The following is the discography of the American rock band The Doors.  Formed in Los Angeles in 1965, the group consisted of Jim Morrison (vocals), Ray Manzarek (keyboards), John Densmore (drums), and Robby Krieger (guitar).  The Doors became one of the most popular rock bands of their era.  Their debut album, "The Doors" (1967), released by Elektra Records, charted at No. 2 on the US "Billboard" 200 and produced the group's most successful single, "Light My Fire".  The album received several sales certifications including a 4 times multi-platinum from both the Recording Industry Association of America (RIAA), and from the Canadian Recording Industry Association (CRIA).  The Doors' second studio album, "Strange Days" (1967), often recognized as their most creative output, failed to produce a hit single as popular as "Light My Fire", though the album sold well commercially but did not reach the same level of success as the debut.  It reached No. 3 on the "Billboard" 200 and was certified platinum in the United States and Canada.  The Doors' third studio album "Waiting for the Sun" (1968), was regarded as an artistic disappointment when compared to their earlier material.  However, commercially it was very successful and reached No. 1 in the US and France, and produced their second No. 1 single, "Hello, I Love You".  "Waiting for the Sun" was the first Doors album to chart in the United Kingdom, where it peaked inside the Top 20.  The album was certified gold in that country by the British Phonographic Industry (BPI), as well as being certified gold and platinum in several other countries. American country artist Crystal Gayle has released twenty four studio albums (one of which was collaborative), seventeen compilation albums, two video albums, one live album, one soundtrack album, and has appeared on sixteen additional albums.

"Not Guilty" is a song by English musician George Harrison released on his 1979 album "George Harrison".
