Because today is Sunday and it is always good to listen to some music on Sundays :) I consider this one of the best end scenes ever made (of a music filme). it is the climax of a whole tension during the film. And of course the actor, sends very well in the end, demonstrating emotion and the feeling that music provides us
I strangely like cliffhangers, like no certain end to the movie, where you are left to make up the ending yourself, or just leave it uncertain. One that comes to mind is inception, when he spins the top and the camera pans away, we're left not knowing he's in a dream or not.
Just to state, if you liked the final song, you can see neesse video here from where it was inspired.
