yo my brother made this song its a banger. Also I wouldn't bother with advice since he doesn't understand music theory. But thank you for trying to help him out.
also, sorry for the seperate comments but in bar 23 to 29, it sounds like a really badly tuned piano. i suggest either moving the e-guitar doen or moving the steel drums up. it doesnt sound good with sharp and flat ontop of eachother. sorry about these comments, i was looking through logs and saw this.
