I tend to listen to albums so barely register in terms of individual tracks. The most underrated Beatles album is Hard Days Night, it has lots of wonder & is on the cusp of innocence turning into duty.and thrice nay. Obviously heard tracks and singles on the radio and stuff but not an album, couldn't name one!
Edit: RE Beatles, nothing pre Rubber Soul interests me, but post that yes pretty much everything.
The way I listen isn't conducive to only knowing one or two tracks as I only play full albums start to finish, so I know 'side two' of everything I own.
There are some acts that I just have no interest in, Nick Cave being an example; we are all different.
