Music in films, the investigating film student's version

i started to work on my paper for German Cinema class. I just watched "The Godfather II" on TV again, and I think it might be interesting to compare the uses of music and violence between "The Godfather" and "Gegen die Wand". Coppola and Fatih Akin? They might have a few similarities. Or at least I want to check it. Second generation Italians in the US and second generation Turkish in Germany. The ghetto of origin. The music as utopia. Violence as connection. Spectacle? We'll see about that.
