Well it isn't copyrighted by a commercial label, but it has Omnimaga copyright on it (except this song, since it weild the name of this site). I have no problem with anyone remixing my songs though, as long as it meets the following conditions:
-It must really be a remix. This mean, not just adding vocals on top or pitching up/down the sound. They must change stuff around too. Else this is considered a rip-off.
-They must not sell the remix
-they must ask me permission first if they want to remix it
-They must post the song at the following URL: http://omnimaga.org/index.php?showforum=123
-If they decide to put the song elsewhere they must post the link to it as well and in their description of the song they must state the http://omnimaga.org
