I listen to what used to be slacker radio The commercials are not to annoying like on terrestrial radio but you can upgrade to be commercial free. Anybody tried the hack for the free Sirius XM? The hack is you pay for a mouth and prior to the end of the month you disconnect the radio. Wait a few weeks and then hook the radio up again. The radio doesn't receive the shut down signal and continues to work. It is supposed to work from what i have seen/read but have not tried it.
