A list of the greatest synth sounds of all time is being compiled, with Pink Floyd's "Shine On You Crazy Diamond" ranked at number 6. Other rankings include a-ha's "Take On Me" at number 8 and Pet Shop Boys' "West End Girls" at number 10, among others. The full list appears to include a range of artists, such as Michael Jackson, Orbital, and Prince, but the exact order and composition of the list are not entirely clear.
