I watch some car videos on youtube (Matt’s off road rescues, Jay Leno’s garage, etc.)
I always get a kick when the various wonderful car noises (tires, engine, etc.) get subtitled as “music” or “applause” - it fits! (That turbo is music to my ears.)
What I find amusing, is when I am watching a movie (or something similar), and the subtitle says something about a conversation in the background, when there is none.
