I'm currently working on a small music album to celebrate my unfinished webcomic's 4 year anniversary.
While Melody for a Duet is never actually used in the webcomic, the song is one of the only real calming songs in the whole original osts. The duet in the track is supposed to represent both of the main protagonists chilling.
You may only use this piece for commercial purposes if your work is a web-based game or animation, otherwise you must make specific arrangements with the artist.
