XM IS THE BEST in my opinion, but as far as music is concerned I believe all genres are covered by both services (just different station names) I think it all comes down to the sports packages...get Sirius if your a big NFL buff, get XM if you like everything else; MLB, NCAA, NHL, FIFA, etc, etc...
I pay $20 month to month for two radios...but you get discounts for paying in advance(longer you pay for, bigger the discount). I can't live w/o it now...BIG upgrade over comercial radio. :hello1:
