Tom Petty and the Heartbreakers: "I Should Have Known It"

Petty wasn't kidding about bringing a bluesier sound to Mojo, his new album (and 12th with the Heartbreakers). The CD's first single kicks off with a caustic riff that ZZ Top would love to have written, and Petty adopts a nasty sneer as he kicks aside a two-timing lover. The slow-boiling rage makes this one of his best bad-love songs, and when he declares, "It's the last time you're gonna hurt me," you know the man is hellbent serious.
