Artists included James Taylor, Carole King, Cat Stevens and Carly Simon. Several songs were played in a row, with no talking between the songs.
From the mid-to-late-1980s and through the 1990s, WMGX was owned by the Portland Radio Group, LLC., which also operated talk radio station 560 AM WGAN, country station 101.9 WPOR and "Oldies" (1950s' and early-1960s' popular music) station 100.9 WYNZ.
WMGX had a unique format, blending classic, soft, and progressive rock with adult contemporary music.
At this time, the station claimed that "[It] never [played] the same song twice [in one 24-hour period]," a boast that it later backed up with a monetary prize to anyone who caught the station doing so.
On March 9, 2006, 29 years after the station's launch, WMGX changed format.
The station then became "Coast 93.1", with a hot adult contemporary format, playing music for the "80s, 90s and Now".
