While I was chatting with a friend at lunch, she mentioned that she rarely (if ever) listened to music on the radio because she never liked any of the music that was played.
That's when I told her about Pandora. Pandora provides a way for people to have "stations" that play music suited to their tastes. They explain how it's done here.
They also have a blog and podcast.
It really is an interesting way to explore different kinds of music and examine what types of music appeal to you. I can't wait to hear what kind of station my friend creates.
