I didn't have the sound turned on when I first hit play, but somehow I knew that it was playing that music. Some of those looked like scary close calls, but it was amusing none the less.
OK so maybe it's my inner immature 13-year-old but I got a good chuckle out of this. I found some of the words that showed up in the glossary amusing. It definitely shows which genres are the cleaner ones, though.
Just kidding. It does look like it might just be some kind of ad, though.
