"Party at the NSA" is a protest song and charity single originally recorded by electropop music group Yacht released in August 15, 2013.
 It was written, recorded, and produced by Jona Bechtolt and Claire L. Evans.
 Inspired by the 2013 global surveillance disclosures, proceeds from the single benefit the international non-profit digital rights group Electronic Frontier Foundation.
"Deep Blue" is a song by English musician George Harrison, released as the B-side to his 1971 charity single "Bangla Desh".
 Harrison wrote the song in 1970, midway through the recording sessions for "All Things Must Pass", and recorded it in Los Angeles the following year while organising the Concert for Bangladesh.
 The composition was inspired by the deteriorating condition of his mother, Louise, before she succumbed to cancer in July 1970, and by Harrison's feelings of helplessness as he visited her in hospital in the north of England.
 Given the subject matter of his lyrics, "Deep Blue" also served to convey the suffering endured by the millions of refugees from war-torn Bangladesh in 1971, as sickness and disease became widespread among their makeshift camps in northern India.
"Soulbreaking" is a song by Canadian rock band The Tea Party.
 It was released as a charity single in Canada to assist the White Ribbon Campaign.
 The charity single was issued in standard and limited quantities, with 100% of the proceeds from the sale of the limited edition of 400 individually numbered and autographed pieces donated to charity.
 The single features "Leaning on Love," the earliest released Jeff Martin solo song, inspired by the events of September 11, with some royalties donated to "The Morty Frank Memorial Fund" - Mr. Frank, a friend of the band, was killed while working at the World Trade Center.
"The Goaldiggers Song" is a charity single by Elton John, released in 1977.
 The song is written for the Goaldigger's charity to provide playing fields in under-privileged areas.
 At the time in 1977, Elton John was living reclused in London; the only time he would go out was to go see his football team Watford F.C. play.
 The single never charted anywhere, as it was a limited charity release-only 500 copies were pressed, approximately half of which were signed by Elton.
 It was available for a cost of five UK pounds by mail-order only and featured Elton and a number of other British celebrities including Jimmy Hill and Eric Morecombe in conversation on the B-side.
 The tapes were destroyed after the pressing, so no other official copies of the recording exist.

"We Are the World 25 for Haiti" is a charity single recorded by the supergroup Artists for Haiti in 2010.
 It is a remake of the 1985 hit song "We Are the World", which was written by American musicians Michael Jackson and Lionel Richie, and was recorded by USA for Africa to benefit famine relief in Africa.
 Initially, in late 2009, it had been suggested to Richie and Quincy Jones—producer of the original "We Are the World"—that a re-cut version of the song be re-released under the title "Live 25".
 Following the magnitude 7.0 M earthquake in Haiti, which devastated the area and killed thousands of people, it was agreed that the song would be re-recorded by new artists, in the hope that it would reach a new generation and help benefit the people of Haiti.
"You've Got a Friend" is a song written and produced by Stock Aitken Waterman and performed by Sonia and Big Fun, and featuring Gary Barnacle on sax.
 The song, a midtempo pop ballad, was released as a charity single for the Childline foundation in June 1990.
 Initially the artists recorded the well-known Carole King song of the same name, but for reasons unknown it was ultimately not used and SAW wrote an original song with the same name instead.
 The cover version was finally released in the 2010 re-issue of Big Fun's album, "A Pocketful of Dreams".
