My suggestion: Release your music in a free/name your own price environment, as well as a paid one(like iTunes). If people like it, they will pay for it. And even the ones that won't will increase your exposure to other potential consumers.
I agree with the basic principle of letting the market decide. But...
Once upon a time, purchasing a CD was both beneficial to myself (I got to listen to music) and to the artist (they got paid). If the music sucked and no one wanted to buy it, too bad for the muso: that's just the way a free market works, yeah?
But, filesharing technology has transformed recordings into something like common or public goods, and you can longer exclude non-buyers from using the product. This allows the consumer - who is acting in self interest - to be better off (free music), but the artist is worse off (no pay). Without pay, there is little incentive for a musician to continue creating music on a full-time basis at the expense of other paid work; the quality and quantity declines, progress slows, and it is no longer in the artist's self-interest to perform lots and put out CDs. In short, there is a market failure.
The question is how to correct that failure.
Two simple solutions: either you put up with more government intervention in your online activities, or you pay for your music. I know what I'd prefer. Indeed, if government intervention of any sort meant that it is no longer in your self-interest to download music for free, then paying for it would only be the sensible thing to do. Market failure corrected!
