Breaking into new territory under the label he co-founded with Jay Park, rapper Simon D (real name Jun Ki Seok, also known as Simon Dominic) dropped his comeback solo single "Won & Only."

Released on the AOMG and 1theK official YouTube channels on Aug. 20, Simon D collaborated with AOMG co-CEO Jay Park (Park Jae Bum) as they sing about an honest man who is simplistic in the way he works and loves.  Epik High's Tablo and his daughter Haru are also both featured in the music video.

"Won & Only" was produced by another AOMG artist, Gray (Lee Seong Hwa), and the track boasts an upbeat bass and soft tempo. 

"Simon Dominic's songs are so pleasant to listen to. And these Jay Park vocals ain't real... so beautiful!" wrote Xiao Lu in a comment posted on the music video.

Prior to dropping "Won & Only," Simon D revealed a self-titled hype track "Simon Dominic" on August 12 to jump start his career as a soloist with AOMG. "Simon Dominic" topped eight Korean music charts upon release.

Prior to the formation of AOMG, Simon D had been signed under Amoeba Culture as part of rap duo Supreme Team with E Sens. The pair has since gone their separate ways.
