Marianne Faithfull is the debut studio album by English singer Marianne Faithfull.
 It was released simultaneously with her album "Come My Way" on 15 April 1965 by Decca Records.
 The double release was a result of different creative directions.
 While the record label pressed Faithfull to record a pop album, she wanted to record an album of folk songs.
 Even after the label suggested an album containing both genres, Faithfull decided to make two separate albums instead.
 In the United States, it was released by London Records with a slightly different track list and inclusion of the song "This Little Bird".
"The Damage" is a song by British neo-progressive rock band Marillion which appeared on their 13th studio album, "Marbles", released in May 2004.
 In October 2005, a one-disc live album containing a subset of the full two-disc studio version entitled "Marbles Live" was released to retail shops in the UK.
 The recording was made at the London Astoria in July 2004.
 To promote this album, the track "The Damage" was made available as a digital download; it is thus the third song to be released from "Marbles" and the only track to be released from "Marbles Live".
 Download-only releases were not yet eligible to chart on the UK Singles Chart at the time, but the single did reach #2 on the UK Official Download Chart.
 There was no physical release available, but a one-track CD version was sent out as a promo (source of cover art).
"Son Song" is a song, played as the sixth track of the Soulfly album "Primitive".
 Roadrunner Records released this song in the form of single in 2001, but the album containing this song was released a year before.
 It is the sixth single released by Soulfly and second from "Primitive".
"Lift Off" is a song by Jay-Z and Kanye West featuring American recording artist Beyoncé.
 It was written by Kanye West, Jay-Z, Jeff Bhasker, Mike Dean, Bruno Mars and Seal, while production was handled by West, Bhasker, Mike Dean, Pharrell, Q-Tip, and Don Jazzy for Jay-Z' s and West' s collaboration album, "Watch the Throne" (2011).
 The song was rumored to be released as the lead single from the album containing additional vocals by Bruno Mars.
 However, Mars never appeared on the song and it was sent to urban contemporary radio on August 23, 2011.
Love Song is an album containing songs sung by Riya from Eufonius first released on August 31, 2005 in Japan by Key Sounds Label bearing the catalog number "KSLA-0019".
 The album contains one disc with thirteen tracks composed and produced by Jun Maeda of Key.

Unapologetic is the seventh studio album by Barbadian singer Rihanna.
 It was released on November 19, 2012, by Def Jam Recordings and SRP Records.

 As executive producer, Rihanna enlisted previous collaborators The-Dream, David Guetta, Chase & Status, and StarGate to work alongside new collaborators such as Parker Ighile, Mike Will Made-It, and Labrinth.
 "Unapologetic" is mainly a pop, dubstep and R&B album that incorporates elements of hip hop, EDM and reggae in its production, similar to the sound of her previous albums "Talk That Talk" and "Rated R" (2009).
"Half of Me" is a song recorded by Barbadian recording artist Rihanna for her seventh studio album "Unapologetic" (2012).
 It was written by Emeli Sandé, Naughty Boy and Stargate, with production done by the latter two.
 It is a chamber pop and R&B song that sees Rihanna deliver vocals in an "experimental" fashion.
 Its lyrics have been described as a "personal essay", with lyrics that discuss Rihanna's unrepentant attitude in letting people into her life.
 She references Oprah Winfrey in the line "You saw me on the television".
 The song garnered positive reviews from music critics, some of whom felt that it is "heartfelt" and "psychedelic".
 Upon the release of "Unapologetic", the song charted in Canada, France, Ireland, Switzerland and the United Kingdom.
 It debuted at number 10 on the UK R&B Chart.
