When I was programming active rock 96.9 the Edge in Gillette, WY. We played Slayer at 7am and we played Sepultura, Lamb of God and a whole bunch more. We also played Zeppelin, Floyd and the Doors and the listeners loved it. XM and serious are much more likely to play the same songs over and over again then most rockers these days. I've got an idea. Why don't you xm fans send me 6.95 a month. That way I'll be the one getting rich off of you and you'll only be throwing away half your money.
