Moon Byul is getting ready to make her next solo comeback!

On December 13 KST, the MAMAMOO member unveiled her new song "G999," a pre-release single promoting her upcoming third mini album '6equence.' 

"G999," which features rapper Mirani, is a song with a fun old-school '90s groove about an irresistible love that has her floating, expressed through lyrics like, "When I see you, I'm weightless / Oxygen is low, but I'm not an alien / Like pulling down, it just moves / Drawn by gravity now what? / I feel the earth move move." The song is paired with a music video with a fun 'newtro' vibe.

Meanwhile, '6equence' is set for release in January.
