I listen almost exclusively to SiriusXM in my car. There are several channels that I really like. I spend quite a bit if time in my car, and always have it on. Plus it's great on long trips, because I don't have to constantly hunt for new stations all of the time.....just 'set it & forget it'. (I also have a Sirius 'BoomBox' out in my workshop, with an externally mounted antenna, that is on whenever I'm out there. And we have the SiriusXM music channels with DishNetwork in the house.)
In my pickup truck, I listen to our local AM and FM stations, as well as WSM 650-AM out of Nashville in the evenings (although Nashville is 500 miles away from here, WSM comes in crystal clear from about 5:00pm to about 6:00am).
On a few occasions I'll plug a patch cord into my iPhone, and listen to my downloaded music in both the car and truck.
