While I seem to be against all new web ideas, Sellaband is the kind of idea that I actually like. You have a band, you want to cut a CD, SellaBand let's you find people that like your music and will buy a chunk of your future profits. It isn't Web 2.0. It isn't disruptive. Music labels won't die as a result. But lots of bands will get to cut a CD that couldn't do it before. A few big names may even get their start this way. By and large though, record companies still have a huge incentive to find good talent, which is why good talent usually makes it to the top eventually.
