Due to getting some messages earlier about using music I would like to mention what you are allowed to do by default with my music.
Since it's uploaded with CC-BY-NC-SA if means you must credit me properly where you use it (Attribution, BY), not use it for commercial purposes (Noncommercial, NC), and must share your finished product (flash, remix, whatever) with the same license (Share-alike, SA).
In addition to the above, I would like to get a PM sent to me with a link and info about your creation and how it uses my music, mostly just out of curiosity so that I can check it out for myself! :D
Should you for some crazy reason want to use any of my music for commercial purposes please send me a PM with the details of your project, relevant pieces, etc. I could also be up for composing new pieces if that would be of interest (this applies to interesting free/unpaid projects as well).
TL;DR: You can use my music for free as long as you credit me properly, inform me of your creation and don't try to sell your creation (usually not the case on here, anyway).
