ummmm........
Extremely normal.
I know someone out there is bound to have an educated opinion. They seem pretty much the same to me, except XM has the NHL . . .
XM has Hockey and Baseball and used to have Nascar.
Sirius has The Howard, Football (NFL), Basketball (at least college), and Nascar.
Both have lots of commercial free music.
Sirius is my choice by a long shot.
You're forgetting my 50 year old Dad.Howard Stern is great. About half of Stern's fan are college educated professionals who listen for the sarcastic commentary and biting interviews. The other are immature jerks who listen for the T&A.
