I don't know where their database comes from (they do have links out to Amazon to sell you the albums), but in some cases they only have ONE album (in the case of Electric Hellfire Club, just Unholy Roller) making the game shorter and more repetitive (I'm sure if I re-took that one I'd get a perfect score, just from learning the differences between re-mixes!). On the flip side, some (like Jethro Tull) include a bunch of compilations, live albums, and special collections, making it easy for even a serious fan to not know a particular cut.
