no, i don't work for xm
and it's clear you don't have it, or you'd be singing a different tune.
XM is a total replacement for terrestrial radio. if you have it, you don't go back. period. why would you?
the business model of terrestrial radio doesn't work, they can't program enough quality in a niche and get enough listeners in a given city to support advertising. terrestrial radio has already lost million of listeners to downloading. satellite is the final nail in the coffin.
