I believe the songs you mention are indeed a regular part of the nationally syndicated Perez Hilton show, which appeals to a younger audience, but I'm guessing they are not part of the WDVD playlist proper and you won't hear them outside that show.
As far as fully transitioning to a CHR, my guess is no. For a couple of months I think Cumulus was testing that idea out, to see if they could pull some of the younger demo away from WKQL and AMP. But they've since put more of their old HAC recurrents back in rotation, especially rock, and now the station sounds more like they did before Cumulus messed with them.
I'm just a listener, though, so who knows what the future brings. We'll see what the June ratings look like.
