Sequential
Aside from being controlled by a robotic overlord, Jack FM (103.7, may the prior occupant rest in peace) is about the worst radio station format known to man. Any sense of continuity or artform about the mix of music is the pure illusion of haphazard numbers, a mere random walk across the sonic landscape.
[That last sentence was totally nonsense, but it was coming off too attractively to edit out.]
Anyway, they followed up the Doobie Brothers with Counting Crows this morning, and — while making no musical sense — it did make me think that those were two genre-busting bands with a bunch of members.
Maybe that’s the game when listing to Jack: try to discern two linkages between each subsequent band played. The warning is that you will get a Pink Floyd to Michael Jackson transition.
