Blue & Grey third track from BTS 'BE' album that was intended for V's own Mixtape has surpassed 70 Million streams on Spotify, being the first B-side from 'BE' to achieve this and surpassed 30 Million Views on YouTube being the most-streamed audio, surpassing even the title track 'Life Goes On' Audio making it 100 Million streams combined in just 84 days which is the fastest for a BTS B-side.

Other than the critical acclaim, V's self-composed song has been the highest charting BTS B-side on multiple charts charting higher than most of their previous title track. V is the only BTS member credited as the main producer of the 'BE' album, which had a tough competition between members and producers on what songs would make it to the tracklist.
