Though it's been gone for more than a decade, I still miss 93 Rock. It's what I listened to in the car most evenings and weekends (I'd listen to NPR during commutes) back before I had options like XM/Sirius and in-car WiFi. The constant repetition and "listener fatigue" from their seemingly limited playlist is possibly what killed them (I heard/read a lot of complaints about that from others who otherwise liked the station). For instance, "Love in and Elevator" by Aerosmith seemed to be in somewhat heavy rotation though they weren't a 'classic rock' station and so much great music was missing from their library. In November 2010 they started playing Christmas music, and in January '11, they came back as Easy 93.1...Which is when I removed them from my presets.
I know the discussion about a proper rock station in the Miami/Lauderdale/Palm Beach markets was brought up in the past and a few including
@DavidEduardo explained why the demographics might make it difficult.
