20. "Sway" (1971)
One of the Stones' heaviest, most devastating songs, "Sway" looks down the barrel of personal apocalypse with grim abandon. Watts' tumbling drum fills mirror Jagger's lyrics about a day that "broke up your mind/Destroyed your notion of circular time," and Taylor (who co-wrote it) tops the song off with a searing, soaring solo. Despite having a deeply Keith-like vibe of lordly wastedness, Richards doesn't play on it – though he did punch in some backing vocals later on, as part of a chorus that included Pete Townshend and the Faces' Ronnie Lane.
