At least you can cancel your subsciption easily (unlike Rhapsody):

1. Log into your account
2. Click on the Media tab at the top.
3. Select Music from the All Media menu on the left
4. Click the Music Unlimited powered by Qriocity icon and a Product Details popup box will appear
5. Click on Music Unlimited powered by Qriocity subscription
6. Click the Cancel Automatic Renewal button

This will stop your subscription from renewing at the end of your current subscription period. You will continue to enjoy the benefits of your current subscription until it expires.
