If you're pondering the purchase of Greatest Hits for its one new track--an ordinary power ballad penned by Diane Warren and produced by Peter Asher--move on. If, however, you're in the market for a summary of the stalwart Northwestern band's fertile 1976 through 1983 period, this will do. Selections from Dreamboat Annie , Little Queen , Dog & Butterfly , and Bebe Le Strange dominate this 17-song collection, which is fleshed out by "Heartless" (from 1978's Magazine ) and tracks from four '80s Epic LPs.
