In 1979, K-102 changed formats again to a tight rotation of album-oriented rock hits with DJs Buddy Hollis, Bo Walker, Alan Michaels, Tom Stevens and Geoff Allen.

By late 1980, K-102's audience share in South Florida had begun to rise; Zeta-4 (now WZTU) had slipped to the number three rock station in the market and was about to switch to a top 40/CHR format since WMJX was losing its FCC license.

In 2012, Sam Zniber became Program Director, steadfastly rebooting the station as "Magic 102.7" (swapping the "j" with a "g") and added some 80s selections to the playlist; this resulted in steady growth, which led to a 5.1% share in December 2013 (from 2.8% in April 2012) in the Arbitron PPM ratings.

On December 8, 2014, Entercom announced that it was purchasing Lincoln Financial Media's entire 15-station lineup (including WMXJ) in a $106.5 million deal, and would operate the outlets under a local marketing agreement (LMA) until the sale was approved by the FCC.
