FreddeGredde are well known for posting music videos on YouTube, but this is easily my favorite of all of them. They mash up 22 different TV theme songs into one massive song, and it’s amazing how easily they transition from one to another. Well worth the time to watch them all, and try not to sing along if you are in your office.
