42. "She's a Rainbow" (1967)
Arguably the prettiest track ever by a crew not known for "pretty" – a pastoral piano melody wrapped in chamber-music strings arranged by a pre-Led Zeppelin John Paul Jones, with child-like la-la-la's swooping through like gnomes in a playground. It's the one essential track on Satanic Majesties, a beautifully constructed piece of psychedelic pop. But the dissonant breakdown and the faintly lewd vision of a girl who "comes in colors everywhere" (a line possibly bitten off Love's "She Comes in Colors") reminds you who is behind it.
