I suppose there could be some argument there for piracy, but I think you'd have to be pretty tight to take it very far. I reckon the promotional value far outweighs any negatives. Unless there are some really awful recordings of your stuff floating around, then it might start to suck a bit. But if you have a recording of someone who played at your night, its only fair to ask them before you share it anyway.

At any rate, as far as downloading them is concerned, I feel MUCH less guilty downloading a set than I do a bunch of songs. In fact I don't really download anything other than sets, and most of them have been willingly shared through this or some other website anyway.
