As a general rule adding music to just about any activity will make it better- taking a cold shower, eating leftovers for dinner, starting a riot, even watching a weather report is more enjoyable when you add music.
So it follows that normally mundane videos would become maximum entertainment when you add the right soundtrack.
Watching these videos with newly overdubbed music added makes me wonder how people could stand to watch such bland videos before the addition of the perfect soundtrack score.
They've also made me wonder why we don't see more auctioneers becoming rappers, because they've got mad flows. yo.
