Scores don't give you fun categories yet, because I don't know how to score it. I need more people to take it!

Even people who know a lot more than I about music probably won't get 100% without using Google. I only got 94% and I made the test! But what scores mean what in the real world? The more I see scores from people I know, and whose level of music knowledge I'm familiar with, the better a sense I'll get. Wanna take the test and tell me what you got? (without Googling for answers, of course :)
