I'm not talking about stealing music. I'm talking about unreleased original material. I've had a few tracks off of people, some from sound cloud too actually, that Traktor just doesn't recognise properly. I've had tracks load with no waveform.. difference to this case is they still played, they didn't unload. Thats's why I asked, might be the same problem but on a worse scale if he plays unreleased stuff, i.e. not bought from beatport, whatpeopleplay or any other reputable digital outlet.
