Well, I'm definitely not the youngest member (I'm 19) but I'm still answering because basically...I'm very bored.
I don't own any CDs, my parents own some Beatles albums and a few LPs and I have everything on my laptop and on my iPod which I carry around to pretty much everywhere.
I do prefer the '65 to '68 output but not because of what critics say. I think it's just because the majority of what else I listen to fits better with the '65-'68 period than with everything before. I'm not really into rock 'n roll and I often dislike covers.
