.org audio

First I want to say how much I love the whole .org thing. I already uploaded my (really bad) video. I will upload all my vids there in the future and it might not make me change all the music. And while speaking of music, what is the audio section for? Is this incase I make a really bad song on FL studio that might fit a freestyle? Is it for voice tutorials? Or is it just because it’s not customized to YYE? I really just want a clear answer to this before I start uploading my really bad FL studio stuff.
