On the one hand, there's the musician who says, "Here, come listen this lovely tune," while the other says, "Here, come listen to me."

Nail hit firmly on head..

I always say a good singer/musician should never get in the way of the music. It's got me some funny looks, but it's my unshakeable belief. My advice to performers would be: If you want your personality to come through the music, don't try to put it there.
