I've been getting PMs from a few people asking if they can use my tracks for such and such purpose. I generally notice these PMs months after they are issued, and so my responses to them are generally useless. I remind you that my music is posted here under the Creative Commons license, thus enabling you to use it for any non-profit purpose without my express consent!
Furthermore, I hereby decree that you can use my music in your work even if there is a chance that your work will make money. That doesn't bother me. Good on ya. Just don't PM me about it, because then I'll read it eons later and feel like a douche.
