ouch, that poll hurt.. My favourites are The beatles, Sgt. Pepper, and Revolver, but I had to vote The Beatles, cos it's got a bit of (almost) everything... Though it was hard...
Hard really to say but i'd go for " revolver" or "abbey road". I named my daughter abbey rose in similarity to this album. Revolver was fantastic for its time, i first got into "help" as my first album, revolver a little later. What really stands out to me was as a child, seeing the big green apple on one side and the cut one on the other, its what first grabbed me, i had a strange fascination with it. You just dont get that with C.D'S do you !
I chose Magical Mystery Tour. It was a difficult choice and I'm not really shure if it will remain my favourite, but right now it's the last one I bought so I've heard it the most in the last few weeks. I think it's underrated because you never see it in the "Abbey Road/Sgt. Peppers/Beatles list of best Beatles albums". And it has some great songs like Fool on the hill and the end of I am the walrus was deafinately an inspiration for Blur's Beetlebum's ending...
Believe it or not, I've never even listened to a Beatles album... They're good, although they're no PINK FLOYD- and, of course, I've heard their songs growing up, but I never got around to buying or listening to all of their stuff.
