On March 12, 2008, at 5:37 p.m., KHJZ began stunting with a loop of "Don't Stop" by Freestyler and "Don't Stop the Music" by Rihanna, while promoting an announcement to come at 3 p.m. the next day. At that time, the station flipped to Top 40/CHR, branded as "Hot 95.7." The first song on "Hot" was "Hot In Herre" by Nelly. The format used an interactive approach and positioned its Rhythmic hit-flavored direction in between KBXX and KRBE. At first, because of its choice of direction, Mediabase had placed KHJZ on its Rhythmic reporter panel, but moved it over to the Top 40/CHR panel as its playlist started playing non-Rhythmic fare. The KKHH call letters were adopted on April 1, 2008.
