Following the trend already set by Tony Stark, when Peter Parker's phone rings at the start of the film, the ringtone plays an odd version of the infamous Spider-Man theme tune, with distinct polka flavour. He also whistles his own theme tune while "battling" Rhino (before he suits up) - adding some light-heartedness that is then smashed into the ground like a sledge-hammer when he pulls his opponent's pants down. And those aren't the only musical references in the film.
