The Ultimate Band List has not overrated itself. Moreover, American Recordings (the creator of the site) doesn't only index their own A&R artists. This list is a database of lyrics, audio files, mailing lists, guitar tabulatures, and of course, Web pages, both official and by fans. If you want to search alphabetical listings you won't be bothered by classifications like 'alternative' or 'techno'; but if you want someone to sort the bands for you, they'll do that, too. Users update the list themselves, so if your favorite band isn't listed (unlikely), you can add it.
