I've been passing the word on to people about Launchcast, which is an internet radio station hosted by Yahoo! You can pay $3 per month to get commercial-free music and better quality, or you can pay nothing and listen to 800 songs a month. The reason I love it so much is that I created my own radio station and rated the artists and albums I like, and Launchcast will play them, as well as other artists and albums that are of the same genre or that are rated by other people who share some of my music preferences. Plus, I can go to an artist's page and randomly rate other similar artists, even if I've never heard of them. And just like that, I expand my playlist and get exposure to other music I wouldn't hear otherwise. And anyone with a Launchcast station can link their station to other users' stations, thus further expanding their music universe. The only things I don't like about Launchcast are that they tend to play a lot of the same stuff often, the commercials are slightly annoying, they're not compatible with Mac OS X yet, and they also stick in some random crap that I would never in a million years listen to on my own. Small price to pay for tonal amusement.
Regular radio, you're going down. Internet and satellite radio give us music fans what we want to hear. So, I share with you my station. Feel free to listen at will, link your station with mine, or suggest new music to add.
Rock On.
