Looks like you can get a free 7 day trial without a credit card! http://www.siriusxm.com/freetrial
It's the way to go. If you do use the credit card/30 day route, you have to end it yourself, or else your card will be
automaticaly charged after 30 days.
I can't come down, I've been set free.
Who you are, and what you do,
don't make no difference to me.
