then you could technically enter "Wind & Fire, Earth," and "Stills, Nash & Young, Crosby

How about:

Crosby\, Stills\, Nash\& Young ?? (OK, just kidding!)

I think your solution is great. It could be enough for me to bring back "The" in my tags. Setting a "sort on comma" bit to yes by default would seeme the best way, Another thought I had was to use a double comma as a sort comma, but that would look a bit nasty (course you wouldn't see it on the player) -- Clash,, The?

Will follow th Wish List with interest
