Launchcast Radio has a "Hair Flair" channel that gives me my fix of hair bands. They also have a "Power Ballad" channel as well. Glad to see I am not the only FReeper that listens to '80's Hair Metal.
You're not...check out my profile page, I list lots of them. I also like the harder 80s metal like Slayer, too, but usually listen to the big hair stuff!
