Also, I still maintain that The Beatles and Pink Floyd are so vastly different from each other that they cannot be compared. I asked around at work (all musicians) and they agree. No one understands why you would even compare the two. What it boils down to is that one is about songwriting and the other about musicianship.
For me, I see enough ****ers on guitar that musicianship has begun to take a serious back seat to songwriting. That's in everything, not just my disdain for Pink Floyd.
I think musicianship and the ability to write compelling music go hand-in-hand, but you're right, just because you can play an instrument like it's a part of your body doesn't mean you will write great music with it.
