Can someone explain to me the Sirius/XM app. On the app it says its FREE if your already a subscriber to the service or that its included with what you pay for your main service whether it be in your car or home. However I couldn't find anything to validate that and so I opted to do the 7 day trial instead of signing up to pay $2.99 a month to have it on my phone for now. I do have XM radio in my truck. A friend of mine suggested I use Pandora instead is that any good?
