Beautiful use of music

Beautiful use of music throughout the movie. And I loved the joy the Antoine character got from music and how music shaped his family's life and connections to each other.
So now I know two Montreal directors whose use of music resonates strongly with me - Jean-Marc Valée and Xavier Dolan. Aside from the use of Pink Floyd (as he did in C.R.A.Z.Y. ) there was a beautiful use of Sigur Rós's 'Svefn g Englar'.
