I have the later ones - White album, Abbey Road, Let it Be on vinyl. All the rest on CD, the remastered British releases. I also have a few of the bootlegs, acquired way before that stuff turned up "officially" on the Anthology.
The Beatles, geez, where do you begin? As a kid, I listened to all that through my older brother who's first Beatle album (birthday present) was A Hard Day's Night back in 1969 when he was 10 and I was 6. From there it was the rest as the years ticked off.
I never get tired of their music. Brilliant on all levels. Picking a favorite is like asking who's your favorite child although if push came to shove, the 65-67 period (Help, Rubber Soul, Revolver, Pepper) would be my desert island discs. But then I find myself listening to Hold Me Tight on With the Beatles, Things We Said Today on Hard Day's Night, Only A northern Song - Yellow Sub. and I'm like, man, Ringo, what a great drum lick, Paul's bass chugging along and I smile, stuff like that.
It's alot like that for me with them, hec, with pretty much all the bands discussed on this forum. I listen to this peerless music in the moment with simple enjoyment but there is also that bonus of time travel that upon hearing a song, it can vividly recall what you were doing, who you were with, the euphoria it creates on so many different levels.
