A little while ago i found http://pandora.com I have come to really like it! What it is, is a site where you can make your own radio stations based on your musical likes. First you make an account. After that you can go and create a new station. To start off the station you pick a song or artist you like and then it will find artists and songs that match that genre. It actually works very well. I have a Punk Radio station and also Ska Punk station. I have found many new bands that i really like from that website. If they start to play a song you don't like you give it a thumbs down and it will not play that song anymore or songs like it.

If you like punk/ska/or hardcore punk check out my profile!
