I think one reason I love listening to the jam-band channel on Sirius is because there’s a good chance I’ll enjoy whatever they’re playing, and due to the nature of jam bands, there’s an equally good chance that I’ve never heard it before.
It also helps that jam-band members tend to be very good musicians relative to the average pop performers.
