I think the spirit of the law is that PGMusic doesn't want to host anything that even remotely looks like they endorse or encourage copyright infringement.

Posting a well known (C) song, even if you paid a fee to remake it on your CD, would probably be frowned upon, because nobody knows you paid for the rights, and others would jump on the bandwagon and start posting (C) songs too.

But if you're asking whether it would be problematic to post a remake of a song that has never been heard outside this forum, and you have permission from the original song writer...

... I'd start by getting that person to post their permission and approval in the same thread where you post the song.

I can't speak for PGMusic, but due to the extremely low likelihood of legal repercussions, I'd guess you won't get any flack.
