Its digital subchannels carry a simulcast of sister station WSSP on HD2, and "Channel Q", Audacy's LGBTQ and dance music service, on HD3.

Unable to compete with WLTQ, they flipped to a Rhythmic Adult Contemporary format during Labor Day weekend in 1996, keeping the "Magic" branding, but changing the slogan to "Rhythm & Romance.

On June 19, 1998, WAMG flipped to the current Top 40/CHR format as "103.7 Kiss FM", and changed call letters to WXSS.

The current Vice President of Operations, Brian Kelly, was in charge of the launch, which included imaging by Mitch Craig.

However, by 2009, WXSS shifted again to a Rhythmic-leaning direction with a heavy emphasis on R&B/hip-hop, dance and pop hits, while playing only the most popular rock music.

In September 2012, WXSS picked up new competition from WZBK-FM, who switched formats from classic country to rhythmic Top 40 as WNRG.
