How do you add music to a map?

[:.DarkMist.:]

I'm making a map and I want to add music to it. I can't seem to get it to work. I tried everything I could think of but when I hit test I don't hear any music. I put the files in sound, music, and the map file in terrains. I've mad maps before but I never put music on them. The file is a mp3 file if that helps x3.
