Show HN: my gamification of YouTube

http://playtubequiz.com

I watch a lot of music videos and wanted to know how well I can identify them. So I decided to create this simple multiple choice quiz game using music videos from YouTube. Videos are muted (but there are short sound hints to jog your memory). I plan on adding more categories and videos over the weekend.

Also check the SOPA inspired blackout mode that requires you to move the flashlight over the videos to identify them.
