i was thinking of getting XM radio and i was wondering if anyone has it. i like a wide variety of music, but i would say i listen to rap/hip-hop the most. however, i am not into hearing about how much Bling G-Unit has. i have been listening to the samples on the site and it seems pretty good. my kinda music. and it is only $9.99 a month and my head unit in the car is XM ready. so it shouldn't cost much. $9.99 is less than buying one CD a month. if you do have it, what are the negatives?
