Interesting use of music in Nicolas Winding Refn's Drive

What makes this use of music so amazing is  in this scene is how "Under Your Spell" by Desire can be heard first as a diegetic sound coming through the walls while we are in Driver's apartment. Then we hear it full blast in Irene's apartment again as a diegetic sound until her husband Standard mentions how much he appreciates how she stood by him while he was in jail. Yet during this time Irene met and fell in love with Driver and you see that expressed with the close up on Driver and Irene  in their apartments respectively  while "Under My Spell" is clearly non-diegetic. The song then goes back to a diegetic song when Driver is leaving his apartment. I just think it is absolutely brilliant the way the Winding Refn used this song how two characters who rarely speak feel about each as well as using it in a way that is clever and feels grounded in reality.
