I cannot pick just one favourite...for I loved everything they ever did! If I had to choose my top three;
Sgt Pepper
Revolver
Rubber Soul

Rubber Soul followed closely by Revolver.....

Abbey Road, followed by Revolver, and then Sgt Pepper and ...well what's the point?

Abbey Road is my answer and i am sticking with it. The cover is clever too.

Let's do this...

1. The Beatles
2. Abbey Road
3. Revolver
4. Sgt. Pepper's Lonely Hearts Club Band
5. Let it Be
6. Magical Mystery Tour
7. Rubber Soul
8. Beatles for Sale
9. Help!
10. Yellow Submarine
11. A Hard Day's Night
12. Please Please Me
13. With the Beatles

I've voted in one of these before. Sgt. Pepper's Lonely Hearts Club Band still remains to be my favorite.

at the moment, it's Let It Be

strangely enough

I don't think that's strange at all. With songs like Across The Universe and I've Got A Feeling. Definitely a great album.

well, most people didn't like it cos they had very little to do with the final product

Meh. I don't really take that into consideration. I listen to it as an album, for the music. Whether or not they were involved in finalizing it doesn't bother me. I think it's a great album, and I enjoy listening to it.

It's still a Beatles album, and should be treated as one.

Rubber Soul for sure just listen to In My Life.
