I have been one of the first XM Radio customers , they have listened to
all my email, even when I asked to add a channel for new rock. They
started to add commericals, sent a email about that too, and now no
commericals(I'm sure others sent email too, but that's not the point), I
have added another XM Unit to my other ride yesterday....I will never go
back to regular radio. If you are wondering who will be around XM Stock is
around 26 bucks , Sirrus is around 3 bucks.

Also with an email you can request songs too!!!!!
