For me, Abbey Road is as good as it gets for the Beatles. I know a lot of die-hard Beatles fans would take Rubber Soul, Revolver, White ALbum all ahead of it, but not for me. I grew up listening to my Dad's copy of Abbey Road and quite honestly, I probably listened to it a lot more than he did.
In my honest opinion, Abbey Road is definitely a Top 5 album of all time, any genre. Just a pure masterpiece
