"50 proof" is one of the personal songs Jae of Day6 made, and the eaJ project is his "venture into music alone". He said this song is his favourite one so far.
I am not the best arranger but I try my best to transpose the song into sheet music. Hope I didn't ruin the song and can let more people know how talented Jae is :)
