That was a hard one. The questions were good, albeit very difficult and extremely varied, but it seems to me the test was overly strict in the answers accepted. It wouldn't even take "Beatles" for "Hey Jude" it needed to be the full phrasing "THE Beatles"!! Same, it wouldn't accept Efron or Carter alone, there needed to be the first name as well, and it wouldn't accept "voice actor" for Lowenthal, it had to be the exact phrasing "voice acting". And again with "Mice and men" that wouldn't get recognized unless you wrote "OF mice and men". It gets rather confusing and annoying when know you've got the right answer. A little leeway would go a long way into making this test a more enjoyable experience.
You should give my general knowledge quiz a go.
