format started with a dance lean, before repositioning to a hip-hop lean, and then alternative; this was done in search of an audience. The station changed branding to B102.7 on August 7, 1998, shifting the playlist to a more mainstream direction the following year. WXYV and WWMX competed against each other due to the similarity of their formats, despite being sister stations. While WXYV had higher ratings than WWMX, the latter station had better advertising revenue, so WXYV was chosen to flip to end the competition. WQSR (2001–2005) On September 8, 2001, at 6 a.m., after playing "It's So Hard to Say Goodbye to Yesterday" by Boyz II Men, WQSR and its oldies format moved over from 105.7 FM to 102.7 FM. (WQSR programming was simulcast on both 102.7 and 105.7 to direct listeners to the new frequency.) Two days later, the WXYV call sign moved to 105.7 and changed back to an urban contemporary format branding as X105.7, positioning itself against WERQ once again. The call sign swap between the two stations took place four days later. In addition, WQSR acquired the rights to Baltimore Ravens games from sister station WLIF, and retained those rights until 2006, when WBAL (1090 AM) and WIYY (97.9 FM) took over. Musically, WQSR's playlist also changed a little, cutting back the pre-1964 songs and some 1980s music was introduced. By 2003, the station was playing mostly songs from 1964 to 1979 with a handful of pre-1964 and post-1979 titles. Jack FM (2005-present) On May 4, 2005, at 10:30 a.m., after playing "Na Na Hey Hey Kiss Him Goodbye" by Steam, the station began a half-hour stunt. Then, at 11 a.m., the station officially flipped to adult hits, branded as 102-7 Jack FM. The first song on "Jack" was "Get the Party Started" by Pink. 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
