Shine On You Crazy Diamond opens Pink Floyd's 1975 album Wish You Were Here and was written as a tribute to Syd Barrett, the band's original singer and guitarist who had left the group. The song is a long, nine-part suite, and its gentle opening has become one of the band's most recognisable passages. Over time, short excerpts have circulated online as standalone clips, shared in tributes, fan edits and nostalgic compilations. Its continued use comes from that association with Barrett and with a period of Pink Floyd's work that many listeners regard as especially emotional.
