For a slightly more commercial take on tunes (and movies as well) there's also the British mag Uncut. You might find it in a bookstore or newsstand with a deep selection, and at $8.95 it ain't cheap. But you do get a mix CD each month, and the March 2003 one was full of very good Bowie covers, including "All the Young Dudes" by Alejandro Escovedo, and "Heroes" by Blondie (circa 1980!).
