Music Isn't Playing

[miru]

I used the YouTube Downloader to get some Alien Challenge music to add to Reginukem's corresponding stages. However, even though I've turned the volume to the standard 255, and made the proper connection to its location in my sound folder, the music still isn't playing at all! Could someone help me?

EDIT: It turns out the Music function was hidden by semicolons. Silly me.
