On September 4th, 2020, at 3PM, WQQO dropped the hot adult contemporary format and began stunting by playing 90s and 2000s throwback hip hop and pop hits, such as Eminem, Fabolous, Fergie, and Fall Out Boy, as a “throwback weekend”, while mentioning “9/8/2020 at 5AM” on every sweeper, and dropping the Q105.5 moniker. Morning show host Eric Chase (formerly on rival WVKS) stated in a teaser video posted on the station’s Facebook page that he gets to do something he has always wanted to do since joining WQQO in 2017. At said time, WQQO shifted back to CHR as "Q105".
