Nice quiz, should definitely be featured. However, I think you can make the quiz a bit neater by using curly brackets in the answers and deleting the hint column, like a fill-in-the-blank, i.e.:
So {don't stop me now} would go in the answers and the user would have to type 'don't stop me now' and the answer column would look like 'So _______'
