Purple Rain: Prince & The Revolution

Slightly different from the other soundtracks in this list in that it comprises only songs by one artist, but as both a film soundtrack and standalone album it works perfectly. The diminutive Purple one is at his best here, whether rocking out with the ferocious, funk heavy Let’s Go Crazy, kicking back with When Doves Cry or letting rip with the climactic title track, which on the album (unlike the single release) features the most amazing extended guitar solo.
