"I'm da boss"

I just finished watching Raging Bull for the first time in a while; what an incredibly powerful film. The very last moments, where La Motta repeatedly mutters "I'm da boss" while shadowboxing, reminded me in some remote way of the ending of Mahler's Das Lied von der Erde. Both endings take a small piece of thematic material, emblematic of the work as a whole, and fade away while repeating it more times than one would expect. When the work finally does end, the audience is left with a sublime echo that resonates more deeply as one reflects on the work as a whole. Anyway, just a random connection that popped into my head.
