Just my opinion, but the Beatles are far from the "greatest" or "best" rock n roll band of all time. Most famous and influential? I'll give you that. But best ever? I was in the supermarket earlier this week, while "Eight Days a Week" was playing. The music didn't stand out, just the singing. And it sounded like "bubble gum music" to me - the sort of stuff 14-yr old girls scream at. Pink Floyd nukes the Beatles IMO.
