Billy is a rock band bass player - he locks in with the bass drum, plays parts which serve the song and sings. That's 95% or more of what he does.

Boring! That's another reason no one's copied him. And as for NV10538... what a racket!?
Don't get me wrong, I'm not a hater... I've encountered him at trade shows too and found him to be very personable. Also I have the Niacin album and like it a lot!! Including his take on 'Birdland'. I'm just trying to answer the OP question.
