How is the client going to get the music?  Is it going to be included,
or will it download it from the server?  I would prefer that the
"default" sounds get included, and that custom ones can be downloaded by
the client.  Though in the case of downloading sounds, we need a way to
make sure that the client won't mix up two different servers custom
music (like two files having the same name).  A hash could possibly
solve this problem.

This can get annoying, since things can get to a state where almost
every gpled game has the exact same music.  Another place to find music
would be to get public domain scores, and convert them to midi, then put
them through a decent interpreter (in terms of sound), though I think a
few projects might do this already.
