I just see it as small potatoes. A lot of DJs charge money for their mixes to cover the costs of tapes, CDs and other miscellaneous expenses. But, I've never heard anyone bitch about not getting paid royalties for their track being on some DJs mix. I've never known any techno producers who, upon hearing a DJ play one of their tracks publicly, going up to that DJ to make sure they'll be reporting their setlist to ASCAP or something similar. And, to be honest, I don't know a soul getting paid DJ bookings who is using stolen music. Most of the people I know who can demand good money for spinning a set are sent the tracks for free via promo. As I said earlier, for the producer who has done everything square, they can get high and mighty and I'll respect their opinion. But, for those who pirate themselves, whether through software, sampling or both, they feel the same to me as a politician with a junk habit pushing for harder sentences on junkies. It gets hard to take after awhile.
