Half Life 2 music

I wanted to make a list of all the Half-life music but I don’t know how. I tried using this code but it didn’t find the songs.

	for k, v in pairs(file.Find("music/*.mp3", "GAME")) do

doing “play [music filepath]” in console works, but this search doesn’t pick up anything.
here is the list im trying to get http://maurits.tv/data/garrysmod/wiki/wiki.garrysmod.com/index8f77.html#Music

“sound/music/*.mp3” perhaps?

lel, worked. I’m going to go home and kill my self to do the world justice.
