Well, personally I'm okay with it, except that I didn't write that song or any of the songs on the album. They are all covers, and since I never intended to sell or make any money off of them, even though I'm the one performing the tracks on the recordings I don't have the rights to the compositions themselves. It's written by the band Kalmah. As long as this competition is not commercial in nature and no profits are to be made I don't see why not, but just be careful. I wouldn't want us to land in hot water over something I did for pure enjoyment with no monetary intentions in mind. Not that this is very likely to happen or anything, just being paranoid.
