Take a look at RateYourMusic.com: http://rateyourmusic.com/artist/the_beatles

While it doesn't list the songs track-by-track, it has a listing of all albums/releases/re-releases and each can be clicked for their specific details. I think much of the same info is also in WikiPedia, but RYM dispenses with all the other encyclopedia information which can get in the way if you just want quick track details.
