I decided that if I could get a free satellite radio receiver, I would try a subscription for a few months. Exposure to different types of music would be my main interest. I'd probably listen at home or at work, as opposed to in my car.
So I am on the lookout for satellite radio giveaways that are legitimate and not a big hassle. At this point I don't have a strong preference for either XM or Sirius. If you have knowledge of such giveaways, please leave a comment!
