madscientist: I wish I knew what's causing this error, but frankly, I don't have a clue. It could be the music file itself, though I doubt that's the case. Im not very good at engine stuff...
My only guess would be that there is something wrong when loading the song from MyLevel, since thats the only thing that differs from most other maps with custom music. I've never had any problems with it before, and it seems like no one else has the same problem :/
You could always try some of my other dm:s where I've used the same way to store the music file, because that way you could tell if it's the MyLevel part or the song module itself that is the problem.
Glad you're so interested in playing my map =)
nude_monster: I'll take that as a compliment
