Could be, but I was importing from the music that comes bundled with Construct 2, so if the file format was wrong, it's still C2 issue (not a code issue, but still a C2 issue <img src="smileys/smiley1.gif" border="0" align="middle" />).
I will keep this in mind though in case I get this in the future.
On a second thought, the import succeeded for me, so regardless of the file format, I should have seen it in the Play parameters. Or if not, then I should have gotten an error importing. So there still is a bug somewhere.
I can post capx and proper repro steps if it's not clear what the problem is.
Cheers!
