D'oh. I forgot about CSN&Y. CCR is just Creedence Clearwater Revival, no commas.

Okay so maybe another strategy would have to be employed... I guess if it was smart enough to deal with multiple commas then you could technically enter "Wind & Fire, Earth," and "Stills, Nash & Young, Crosby," but that would look really dumb in your MP3 tags. Either that, or have a bit set aside to "turn off" the automatic comma parsing for artists such as the ones you mentioned.

Sigh. Good catch.
