Universal Music Group's recent news that it's releasing a big part of their catalogue for free download through a new service called SpiralFrog has been getting lukewarm reviews, as I think it should. The idea of having to listen to a 90-second ad in order to download a copy-protected WMA file that won't play on a iPod, that can't be burned to CD, and that expires in 6 months is freakin' stupid, to put it mildly. Mark Glaser over at the PBS MediaShift blog sums it up pretty well right here.
