The vocalist just released his first solo project song "You're All Talk". It's about a man who just keep making promises, but doesn't keep them with the excuse that he's busy. He actually revealed the title of the song before in May, through 4men's mini album 'Thank You'.

The song is an R&B song, and it showcases Shin Yong Jae's emotional voice perfectly. After this, the other two 4men members will be releasing their own solo songs under the concept 'Heaven' over the next two months. 

Their agency Happy Face Entertainment stated, "It will be a good gift to fans who've been waiting to listen to the voices of not 4men but Young Jae, Kim Won Joo, and Shin Yong Jae. We ask for your love and support."

We will update this post once the MV is released!
