There's way more Metallica songs I would not buy than songs I would. That's probably true of Aerosmith, too. I don't think there's even one Van Halen song I would want. The only Muse song aside from "Hysteria" I even know is the one that got played at my work, and that's the only reason I know it.
Honestly, of all the "GH artists," the one that would make me happiest is probably Taylor Swift. But no way in hell do the mods stir the pot this much if it's Taylor Swift.
