How do I go about being able to listen to every altlanta braves game?

I live in tennessee and we don't have any braves games on our am/fm radio...i was think maybe sirius or xm, but the problem is would I be able to actually listen to just the braves games? the reason i ask is because i want to be able to listen to the game while im at work and we aren't allowed to pull up the website at work so it wont work on the computer. so what do you think???
