How many Beatles albums do toi own and which one is your absolute favorite?

All. My favori is Revolver.

I have all of them. I honestly can't pick a favourite. If I had to, though, I would probably pick Please Please Me.

I had to sell off part of my collection several years ago, but I still own 16 LPs (vinyl). I also have the first 45 I ever bought (Hey Jude / Revolution), some CDs, and a Beatles sound sheet (pictured below), as well as a bunch of vidéos on VHS tapes.
Out of the albums, I think I'd have to say that 'Revolver' is my favorite.

Technically, it's my dad's collection (though we share it) but he's missing the last two albums. My personal favoris are Sgt. Pepper's, Magical Mystery Tour, and Please, Please Me :).

I have all of them. Abbey Road is my favorite.

Actually it's my dad who owns all the albums, though I have them all on iPod. (I decided not to take the version of l’amour Me Do where Ringo doesn't play the drums, though). And my favourite Beatles album is, and has always been Help!
