BTS rapper and lead dancer J-Hope dropped the surprise new solo track Blue Side on Tuesday (March 2). 

Blue Side began life as an outro track from his 2018 solo mixtape “Hope World” and – with the help of frequent collaborators Hiss Noise and Adora – J-Hope made the song complete by adding lyrics and fleshing out the melody. It was released on the third anniversary of the arrival of “Hope World”.
