 On January 9, 1984, WABX's long-term reign as a high-rolling rock station came to an end with the song "When the Music's Over" by The Doors, after which the station became "Class FM", WCLS, with a soft rock format.However, the adult contemporary field in Detroit was as crowded as the rock format had become, and "Class FM" was not successful.At this same time, the station was sold to Metropolis Broadcasting.
