Hello, is it okay to add GPL licensed work and Creative Commons licensed work in one archive and distribute it?
For example: A GPLv3 licensed game, bundled together with "Attribution-Noncommercial-Share Alike 3.0 Unported" Creative Commons licensed music, packed together in one archive.
Somehow, I have got this idea that it might not be supported (since the gnu site says gpl and cc can't be combined), but on the same time I've seen a lot of games do this. (for example:
Mania Drive)
I'm planing on creating a multiplatform 3d racing game under the GPLv3, and on the same time ship it with (different CC version) music from Jamendo, so I would appreciate if someone could share any light on this matter.
(Off course, I'm not going to hold anyone responsible for any damage or economical loss that could come from an incorrect advice, etc, etc... you get the point

)
