How do you add music?

[Wingy]

Remember, if you set the number to -1 no music will play. Also, when you're going into another section with different music, if you had music in the previous room you should set the music in the room before the new section to the current music playing, so if you go into the next section, music changes, then you go back to the old section for something, the music will change back to the old music that was playing.
