How do you unistall Napster?

You have to call their number 866-620-1137 Monday through Friday 9am to 10pm and weekends 9am to 5pm EST and tell them you want to cancel Napster first so they will stop billing you if you haven't done that already then if you are using Windows go to start > control panel > add and remove programs and remove the actual Napster program from your computer.
