Slacker Radio

Slacker Radio is the best music solution I've found on Windows 8. You can listen to pre-made radio stations of the type of music you choose, or you can define your own stations and pin them to the Windows Start Screen. I used to listen to music I already owned on CD's, but I'm finding myself turning to Slacker Radio more and more to listen to all the music I like.

Price: Free, or you can subscribe to Slacker for a fee to get rid of commercials.
