Musicians of Brand New Music held a time of reflecting on 2014 and preparing for 2015.

On December 5, Brand New Music released their family project single "Brand New Year Vol.3 Brand New Day" and its music video.

San E, Verbal Jint, Bumkey, Kanto, and other artists of Brand New Music participated in the song. They took their own parts of the song to tell their own stories.

Their rap flows on a rhythmical beat and a warm melody. The R&B hip hop genre of Brand New Music is very much evident in the song.

In the music video, all the artists of the agency appear to portray a family-like atmosphere.
