Although it's definitely not the Beatles' best album, "Revolver" is still probably my favorite album. It's not perfect, but it has heart like nothing else. "Eleanor Rigby" might be my favorite Beatles song of all.
The Beatles' Abbey Road. If it were a life & death situation and I was forced to chose my favorite album of all time, it would be Abbey Road, right before Dark Side of the Moon. there's so much feeling attached to it. It really speaks to me.
