Roger Ebert posted a great article on upcoming 'copy-protected' Audio CDs that, among other things, won't play on Macs or DVD players.

It got me thinking about a world where music was able to reach every corner of the world without people having to buy it, where they could experience new music they wouldn't otherwise be exposed to. Oh yeah, it's called radio, and the labels love it to death. It's how they make their stars.

Radio listening at work has been dropping in favor of internet streams and personal music collections on CD or MP3 for a decade. As digital streams and MP3-CDs continue their inroads into car stereos, I wonder when the labels will realize that radio is no longer the best way to publicize their artists, and that to push awareness of new music to those with the financial resources to buy new albums, they'll have to turn to the net, even if they can't instantly monetize it.
