The WCZY call letters had belonged to a heritage easy-listening radio station in Detroit known today as CHR formatted Channel 955.

The station aired with its intended easy listening format, and was provided jointly by Englewood, Colorado-based syndicator Jones Radio Network, and Salt Lake City-based Bonneville Broadcasting.

This tape-based music format provider had no desire to enter the dwindling, easy-listening radio programming market.

Since then (now under the Westwood One umbrella), WCZY has transitioned to programming of mainly local origin and has also dropped its former "Lite Hits" slogan, now identifying as simply "My 104~3".

In addition to standard music programming, WCZY-FM and its sister station WMMI-AM also provide coverage of local high school sports in the Mid-Michigan area.
