No I don't think they've flipped & I don't listen to enough top 40 to really have a handle of who is playing what, but I was with someone who had PRO-FM on the other day for about 15 minutes. It was late morning & the only current I heard was Cruise. Other than that it was Before He Cheats by Carrie Underwood, some Adele song, and How Far We've Come by Matchbox Twenty which I didn't feel was even big enough for any station other than a hot AC to be playing at this point. When I hit the seek button on XM & catch Z100 & KISS, the music seems to be a whole different ballgame. Is it a midday thing with them? To me, the format itself is heavy on currents & when I hear the Boston top 40 stations I get that impression too. I'm not about to take the time to compare playlists on mediabase. Is this a midday thing, request hour, or something Cumulus does with their top 40 stations?
