On the offchance that anyone would be looking for the soundtrack to the Arcade version of Ghouls'n Ghosts, I found it here with some pretty difficult searching :)

Offchance indeed, thanks! I'm always looking for G'nG music, especially the bonus tracks that appeared in Capcom Classics Collection.
You might be interested in this topic, too, if you're a G'nG fan, and I think it contains arcade versions of some of the games:
