 WFMK has long been one of the most popular and most highly rated stations in the Lansing area.When WHZZ in Lansing, Michigan abruptly changed format from Contemporary Hit Radio to Adult Hits in 2005, WFMK, along with WQHH and WJXQ temporarily took advantage of the format switch, touting the many CHR artists on the station until WFMK's sister station, WJIM-FM changed format from oldies to CHR a few days later.In 2010, WFMK shifted to an all-Christmas Music format for the holiday season.
