Late yesterday, a Friend of Unfair Park suggested that Cumulus Media's going to rebrand 93.3 on Your FM Dial as a pop-40 station -- as in, Justin Timberlake and the Black Eyed Peas. Maybe so. But this much is (almost) certain: Sooner than later, KDBN-FM will most likely be known as ... KLIF-FM, shades of Gordon McLendon. So suggests Cumulus's request to the Federal Communications Commission filed on Monday, which would resurrect a call sign that hasn't been around since 1966 and has radio boards speculating about all kinds of possibilities for the frequency.
