Not a problem at all! All of my music is licensed under a Creative Commons Attribution Non-Commercial No-Derivatives license, which effectively means that you’re more than welcome to download it, share it, post it on Facebook, and otherwise distribute it without any problems — so long as you attribute it, don’t sell it, and don’t modify it. 🙂
I really appreciate your asking — it’s also prompted me to put the CC license details onto all the tracks I’ve uploaded so far this year.
