XM 3 day trial

On Sunday, I did a 3 day trail of XM. I liked it. I thought subscription radio was a silly idea, but it's really quite nice. About 100 crystal clear, commercial free stations that play non-stop. Sounds cheesy, but I'm really considering popping for it. I've had a pretty bad problem with broadcast radio.....it's horrible. Too many commercials, the same 12 weak songs all day. I listen to mostly talk radio since the rest is almost completly un-listenable. I don't want to spend any more money, but I figure what the heck 13 a month won't kill me.
