Alright, I had an opportunity to try XM for about three weeks and I enjoyed it quite a bit. Never tried Sirius. So, I wondering if those of you who have experience with both could chime in. I don't listen to radio a lot right now due to programming content, commercials, etc...... My listening habits are pretty eclectic (Jazz, R&B, Blues, Funk, Rock, Reggae, some Hip-Hop/Rap, Smooth Jazz, Classical) depending on my mood. Which offers the best value?
