Thanks for the help guys, perhaps I should have explained it in a bit more detail. We are not using trying to sell the audio that is uploaded through the audio module, the file we upload is a simple playlist file, in fact we just want to turn the audio content type into a product so we can add the full audio in a product option of mp3 or flac just like in the livetest here http://livetest.ubercart.org/product/cha0s-jams-recursion-emerge is this possible?
