WMUS (107.9 FM, "107 MUS") is a radio station broadcasting a country music format in Muskegon, Michigan.

In recent years, WVIB and WUVS-LP, both FM stations, have filled the hole for urban radio in the Muskegon market.

In October 1999, "Z108," was sold from Goodrich Radio to Connoisseur Communications who began dropping hints that a change was coming to the station.

Some interpreted the hints to mean that WSHZ would change to a CHR format to challenge former sister station WSNX, particularly when it was learned that Britta Cleveland would be part of the new local air staff.

WMUS broadcasts in HD Radio and as of October 2015 aired a rebroadcast of the iHeartRadio feed featuring pop-R&B singer Jason Derulo as guest DJ.
