Thanks Apoxode. It won’t be a damage or so if there is now way though. But, I’d prefer to change the licensing if possible.

I think it will most likely not be an option because of the commercial aspect of licensing. There could be a negative impact on commercial remixes if the original artist changed their commercial license to non-commercial. That would make the remix non-commercial as well, and would affect any usage (ads, films, digital stores, etc). This is particularly tricky with multiple sources.

My best advice is to get into the habit of unselecting “Publish Now” in submit samples/remixes when you upload, because then you will more likely see the license selection. This is because by pressing ‘enter’ it will proceed to upload, even though you can’t see the area for license selection.
