On December 15, 2008, CBS Radio announced that it would be swapping WQSR and four of its other medium-market radio stations to Clear Channel Communications for two radio stations, KLOL and KHMX in Houston. Clear Channel took over WQSR at 11:59 p.m. on Tuesday, March 31, 2009. After playing songs at CBS Radio's Baltimore studios such as "End of the Road" by Boyz II Men, R.E.M.'s "It's the End of the World as We Know It (And I Feel Fine)" and "Goodbye Stranger" by Supertramp at roughly 11:57 p.m., the station went to dead air as Clear Channel officially took ownership of the station. Shortly thereafter, the station returned to the air at the Clear Channel Baltimore studios. The sale also resulted in the station reuniting with former sister WCAO under common ownership for the first time since 1998.
