I personally don't listen much to KTCZ, for a couple reasons... 1) I hate the way their stopsets are programmed. And 2) when I want to listen to AAA, I'm generally not looking to hear the Pink, Bruno Mars, etc. stuff that I can hear so many other places. Usually for AAA, I prefer stations that balance the commercial with the slightly obscure (i.e. WXRV, WRLT, CHHR).
Of course, that's a matter of personal preference. I generally respect what KTCZ is doing & am happy to see a commercial AAA success story out there.
I have no problem with KTCZ being on the AAA panel, at least for now. For the most part, their playlist is wholly current/recurrent AAA, albeit a more commercial/Hot AC-leaning AAA. They've always programmed in the Pink/Bruno Mars stuff (at least since I've been following them), but they're somewhat selective in the songs they play by those artists (i.e. "Don't Let Me Get Me" flies, while "Get the Party Started" and "Most Girls" probably wouldn't. At least I hope they wouldn't.
) KTCZ also plays a decent amount of indies and non-singles. And like chrocket87 mentioned, there's an NPR AAA in the market, so I suppose KTCZ can go for the more commercial side of things. Certainly I've seen panel assignments that made less sense.
It's also worth noting that "Locked Out of Heaven" got quite a bit of airplay on a fair number of AAA stations--including some respected outlets like WXRV and KSGR. "Give Me Just One Reason" also got spins on a few stations, though I tend to think that was more because of the connection to Fun. than the song itself.
All that said... "Blurred Lines" and "Stay" stick out like a sore thumb on that playlist, at least on paper. To my knowledge, Thicke and Rihanna are pretty recent additions. Hopefully, their presence is short-lived. But, if that becomes the trend, I'll probably hop on the "move KTCZ to Hot AC" bandwagon.
