I think we've gotten off track of the original question, and I take full responsibility for that by mentioning TAB. I just mentioned Guitar Pro because they do have tons of official TAB's that are for songs that are copyrighted.

It's not about notation. It's about providing BIAB songs/arrangements that are copyrighted, (copy written ?).

I know there would be fees involved and I'm going to give Guitar Pro the benefit of a doubt and assume they've paid those fees. Those "song packs" could be sold separately which wouldn't cause the price of BIAB to go up.

So again, hey Peter Gannon. LOL
