Update: Oh boy. 15 minutes of upload time left. Feel free to request some stuff, though.

Uploader of the more obscure TF2 music that should be heard. Also, reuploader of some of the bad quality TF2 music here. I try to make them clearer and better to listen to. 
WHEN I RUN OUT OF UPLOAD TIME, I MIGHT MAKE A NEW ACCOUNT OR UPGRADE TO A PRO ACCOUNT.
