Rocking : the Quiz

Check out MSNBC for the musical Rocking: The Quiz. I socred a 68% but considering some of the questions were difficult, didn't think that was too bad. Then I looked at how everyone else fared and thought, hey, I know a fair amount of music trivia after all. Out of (so far) 7576 quiz takers, the scores have been:

0-10% = 0.1%
11-20% = 0.6%
21-30% = 3.1%
31-40% = 16%
41-50% = 22%
51-60% = 32%
61-70% = 15%
71-80% = 8.3%
81-90% = 1.4%
91-100% = 1.6%
