A friend was raving about this music site called Spotify. Basically, it is a free music site with ads every 10 songs or so. I suppose it's like having a radio station that you can choose your own music. You can also sign-up and have music ad-free.
This may, some are saying, be the end of itunes but here is my caution. If none of us ever pay for music will music cease to be written or will it just become more egalitarian and less in the hands of the few? Only time will tell.
