Do radio stations listen to each other?

This morning while driving to work I accidentally hit the radio preset for Alice 97.3, which I normally avoid like the plague in the morning so as not to hear the utterly mind-numbing Sarah and No-Name. Before I could hit another preset, I realized they were talking about that actor guy who was killed off on Prison Break, and who just the other day killed the teenager who was riding in his car after a high school party. The whole story is intriguing so I took a listen. They mentioned how in his youth he had gotten into trouble by among other things, stealing a jug of wine or something like that. And how his rebellious streak landed him a gig living with then-pastor Joe Simpson, Jessica and Ashlee's dad. And then they moved on to some story about Michael Jackson and how he's being implicated ONCE AGAIN by some kid claiming that MJ molested him...AND stole his writing to use in songs...all when he was between the ages of 2 and 14? It was at that point that Sarah started making some comments about MJ's song PYT (Pretty Young Thing). Eventually I couldn't take it any longer and changed the station.

Anyway to make a long story short, no less than 5 minutes later, Movin' 99.7 was playing Pretty Young Thing. Which they followed up with UB40's Red Red Wine.

Coincidence? (now do you expect to hear...it's no coincidence...this is Sharks territory!...like I do?)
