Personally, music is more important than how the game looks. That's just the looks, not the physics, Ai and all that.
Is it a coincidence that my 2 favourite games are also the 2 with the best music?
I tested something a few days ago. I played Super Mario Galaxy without sound. It was still good, but not even close to as good as it normally is.
Then, I played it in Black & White, but with music. That was tons more enjoyable. (Lacking the colours was definitely a letdown though).
