and Winding Road" by The Beatles and "Changes" by David Bowie, WJMK began stunting with sound effects and clips of a man giving occasional comments, such as "What's going on here?" and "It's almost time to start." One hour later, WJMK flipped to classic hip-hop, branded as "104.3 Jams", which began with an introduction by legendary rapper, actress, radio DJ, and station voice MC Lyte. The first song on "Jams" was "Hypnotize" by The Notorious B.I.G. Entercom applied to move the WBMX call sign to 104.3 from its sister station in Boston to match the new format; the change took effect on December 4, 2017. The WBMX call letters had previously been used by new rival WVAZ from 1974 to 1988. In addition to WVAZ, WBMX also competes with WPWX and WGCI in the urban radio market. WBMX is the second station in Chicago to use the "Jams" moniker, the first station being WEJM in the mid-1990s.
