Rock ‘n' roll rivalries have traditionally played out in the music press, but, occasionally, the acrimony spills over onto the lyric sheet. Lynyrd Skynyrd's prideful “Sweet Home Alabama” doubled as a critique of Neil Young's scathing “Southern Man”; the Foo Fighters' first-album salvo “I'll Stick Around” (with its chorus of “I don't owe you anything!”) was widely assumed to be about Courtney Love. Warning: some scenes may contain bruised egos.
