Here's WKSC's playlist from the last couple days:
Top-40 chart Found here: https://hitsdailydouble.com/mediabase_chart_details&fmt=H1
Only song seemingly missing from the CHR stations here is "The Bones" by Maren Morris. I'm surprised they're not playing that song in specific. I've heard it most everywhere else aside from WXSS (103.7) in Milwaukee which leans extremely Rhythmic to protect it's sister Hot AC station WMYX. Must not be testing well in Chicago, as I have not heard it on B96 either.
As for Hip-Hop, WKSC always played it. They leaned extremely Rhythmic between 2007 and 2013. They spent 2001-2006 or 2007 being the "Anti B96" and then they literally basically became B96. That was when I quit listening almost completely because it sounded really annoying and tacky. B96 began evolving back to Mainstream CHR in 2010 or so. They were full blown Mainstream CHR by the time WKSC brought in Tommy Austin who revamped the format to sound more like a Top-40 station again.
