I'm not suggesting anything more dramatic than them playing a current or two within pretty much the exact same playlist they have now (albeit probably at the cost of the little bit of 70's rock they play that has heavy overlap with 93XRT and The Drive). If it came off as otherwise, I apologize. If you did understand what I was getting at, could you explain why it would be such a major, audience-alienating shift to play, for example, Chris Cornell's cover of "Patience", a recurrent like "S.O.S. (Sawed Off Shotgun)" by The Glorious Sons or a 2010's hit like "Gold On The Ceiling" by The Black Keys, once or twice in an hour of pretty much the same music they're playing now?
I don't doubt that iHeart did an insane amount of research to make the playlist work for the Chicago market. They also probably spent a lot of time listening to their would-be competitors to know what the audience is listening to and what they are lacking. They are literally playing a huge plethora of songs that have been neglected (Nirvana, Soundgarden, Kings of Leon, blink-182) or completely absent (pretty much everything The Loop played) in the Chicago market. It's smartly programmed, but I have to wonder what happens when the "new station smell" wears off. Right now there's a gradual building of curious listeners, but what happens six months from now? I think the current playlist is extremely intelligent and should hook people, but eventually they'll have to start mixing it up. I am curious to see what they'll do when they have to start gently adjusting the formula.
