I used to like Sirius XM, but have come to realize that they had a very limited play list rotation. You don't notice it quite so much in a car, you just surf to another channel. We play it in some of our operating rooms, so we tend to just put it on and let it play. When you listen to it continuously, it's not much more that 15 to 20 songs that play regularly. It does change over time, but for a period of time, it's the same stuff over and over. When I use it in my car, it isn't as noticeable because I am surfing channels fairly often. Then I started to wonder why I am always surfing...
It is a lot better on some of the channels when they have guest DJs. Those people usually have fresh music, or at least a fresh play list. But if you just put it on Hits1, BPM, the Spectrum, etc., and listen, it's the same stuff over and over.
