Diagetic, Non-Diagetic, Pleonastic and Contrapuntal Sound

We see that in this scene a brilliant example of Pleonastic and Non  sound used effectively. We see the main character Nathan and the rest of them using diagetic speech effectively (speech). We also see the use of music being played through their headphines and graually the volume being raised up, this helps represent the youths of today the type of genre they listen to as we hear the famous Lady GaGa song just dance so this proof that they are somewhat socially active to keep up to date with the music listened today.
