Any free Ultima-style music?

It looks like I'm going to have to drop the music from the packaged version of Nazghul because as far as I can tell it has a noncommercial use restriction. I wonder if anyone has any leads on some basic free Ultima-style music that I could suggest as a replacement. The engine just uses ogg files, with a simple schema file that defines which songs get played where, so I can easily replace stuff if I can get replacements. Currently there are fifteen songs, all taken from mfiles.co.uk. I still need to bounce an email off of mfiles to verify that the nazghul folks didn't obtain special permission. Actually I'm having trouble deciphering the situation, but I figure it's better to pull now so that we don't ship this stuff in F12. - J<
