They're not aiming for someone has time to sit and listen. They're targeting working commuters in target demographics that advertisers want. Some of them are driving for less than 10 minutes per trip. The music is meant to be a filler in between the advertisements.
There are no ads. It is a subscription company. Not even a DJ it's all an automated loop as far as their music stations go except Willies Roadhouse has some persons on at times. One is his daughter. I bet the other music stations are playing the same song loop they were playing in 2017 when I bought the truck.
