The music on Magic 103 was mostly album cuts from singer-songwriters of the 1960s and early 1970s, presented in four-song blocks with minimal talk.

WUSL had switched from easy listening to a soft vocal format similar to WMGK, but with a shorter playlist of more familiar songs.

Craig returned in the spring of 1990, and again hosted a contemporary jazz show, this one running on both Saturday and Sunday nights from 7 p.m. to midnight.

Easy 101 had a large number of listeners, and most of them stayed with the station when it became B-101, causing WMGK to slip in the ratings.
