I’ve only listened to a few of your pieces thus far, but I’m rather liking what I’m hearing! I could very much seeing myself using some of your work.
(Indeed, your posting is quite timely–a one-week game development competition is coming up on GameDev.net, and I’ve been a little concerned about coming up with music for my entry.)
(The only caveat that I have with regards to using your pieces is that I think that I’ll likely end up converting your MP3s to OGGs: if I’m not much mistaken, OpenAL loads the latter, but not the former.)
Finally, thank you very much for releasing your work under the Creative Commons licence–that is quite a boon.
