On May 22, 2013 at 5PM, after playing Kesha's "Blow", and a goodbye message, followed by Simple Minds' "Don't You (Forget About Me)", WNTR began stunting with micro-formats (Rock as "Rock 107.9", all Garth Brooks as "Garth 107.9", Christmas music as "Yule 107.9", all boy bands as "Heartthrob 107.9", all Midwestern-born artists as "107.9 Heartland Radio", and sounds of nature as "Earth 107.9"). The following day at 5 PM, an AC format was introduced under the name "107.9 The Mix", with Dave Smiley from sister station WZPL launching the station with Fall Out Boy's "My Songs Know What You Did in the Dark (Light Em Up)".
