Hey - why not create an online radio station that fits you perfectly? If you haven't heard about it, Pandora does just that. You create any number of stations that match your musical taste.
It's pretty simple and it's free. You simply create a new station, enter the name of an artist, and Pandora plays one of their songs to confirm they've got the right artist. Pandora then uses the power of the Human Genome Project to find other artists with similar qualities and creates a streaming radio station for you.
As songs play, you can click on Thumbs Up/Thumbs Down icons to help them learn more about what you like or don't like.
You can check it out without even registering, then if you like it just create an account (your song doesn't even stop playing).
If you don't want to be chained to your computer to listen, there is also a fee option. That is $36 per year and allows you to stream to your home or to certain mobile phones.
