Striking a perfect balance between honest self-reflection and fierce, unbridled catharsis, this might be one of our favorite breakup albums of all time. One minute, Alanis' otherworldly voice sounds tender and heartbroken on the delicate ballad "Torch." The next, her tone turns splendidly icy, backed by a torrent of synths on the wickedly smart character assassination "Straitjacket." The emotions here are as big as the end of a relationship, and there's no singer we'd rather feel them with.
