Understood, thanks.
As I say, I'm sorry that my first post is negative, as I've been lurking, downloading and playing files from this site and others since the early 1990s, and there are some absolute belters out there, which I intend to finally get around to praising with the credit they definitely deserve!
When I'm brave enough, I may also finally upload some of the stuff I did back in the 1990s with ScreamTracker, but was never brave enough to share.
As I have a tenuous relationship to the original version of The Gael, by Dougie Maclean (I was a member of the Loch Ness Project during the 1980s & 90s, and was involved in setting up the exhibition for which the music was originally commissioned) I recognised this instantly. I've never come across any other commercial work being used without it being explicitly stated as such. However, I accept what you say about this being acceptable (assuming no commercial benefit comes from this).
Thanks for your reply.
