The headline may pretty much says it all, but Sasha Frere Jones at the New Yorker writes a little mreo ind-depth on what exactly is going on. A couple of details:

1. it's happening via twitter
2. and he said "I am going to tweet 3 new songs this week. I can't be bothered with all this trying to sell you music. It wastes valuable time."

i love how this whole music thing is getting set on its head from big to medium-sized artists.
