I really like Greg Birkumshaw in this one

Greg Birkumshaw as Music has some moments that stayed in my mind. The timing is good, and the emotion comes at the right moments. It is not too loud, but I still remembered the performance after watching. The acting feels natural, and I can follow the feeling very easily. I think this work helps the movie a lot, even when the story is busy. This is only my personal view, but the performance changed how I enjoyed the film.
