My music doesn't work, please help.

[Wapez]

Sup guys, I'm making a custom story, and in this map I want to play different music. So I downloaded an .mp3 file, and switched it to .ogg file by simply changing the ending of it from "'music-name'.mp3" to "'music-name'.ogg." But when I try the map, the music just won't play. I'm getting irritated. If I did that the file-changing wrong, or if its any problems with my scripting, please tell me. Thank you.
