The station is carrying The Diva Diner, from the Tom Kent Radio Network. It runs during the afternoon, apparently for a few hours on a daily basis. All the songs are by female singers. As this is a syndicated show, I would guess the network has done research indicating such programming can work on an A/C type station.
