Custom Music for UI?

[preston566]

Well, herea goes. I AM making a custom UI, for a project. But I need
to know how to make the music I WANT to play. Right now, no music
is existant, but I need to get MY music into play. If anybody knows how
to do that, please point me in the direction.

2. My UI has been built. However, there ARE no option buttons. No
multiplayer, no settings, just a screen. If someone knows why this is
and how to fix it, please share.

Thanks,
