I have had Xm radio for around 6 mos. It's definetly worth the $10 a month. Either one is good, they just have different ways of going about it. My personal favs: Liquid Metal/Bone Yard/Extreme comedy/Nascar live. You will never go back to "regular" programming. Check out the "Drew Garabo show" its fucking funny along with the "Monsters of the Midday"
