First of all, why would you want to? It’s a great service, very inexpensive (less than the cost of one CD per month) and works very well with broadband services. However, you really want to cancel, you need to call RealNetworks who is the owner/operator of Rhapsody.

Here’s the number to get customer support or cancel if you still need it: 1-866-597-5465
