2. Electro Plays "Incy Wincy Spider" On The Power Conduits (The Amazing Spider-Man 2)
The final fight between Spidey and Electro takes place at a power station, and begins with Electro flying between power conduits, while slamming Spidey into them along the way. All this movement emits a number of peculiar dubstep-esque sounds from the conduits, which on closer listening actually spell out a tune. The tune? Incy Wincy Spider, of course, explaining why mid-way through Electro's little musical number, Spidey declares, "I hate this song." It's a difficult one to catch the first time around, both because of the distorted sound and the musical notes being separated by Spidey being slammed around, but it's nevertheless a clever aural reference to its arachnid-inspired protagonist.
