I have a PhD in music appreciation from Juliard and am the nation's foremost music critic. My Wikipedia page says this is true, and so it must be (Note to self... update Wikipedia page). So who better than me to write this test?
And its going to be objective too, and based on clinical trials, empirical data, and polysymphonic-audiological-compositions. (songs that rock!)
So if you think you've good taste in music, take the test to find out whether you're a tool of the major labels, or actually an educated listener.
Also... since its the internet, there's nothing stopping you from opening a new window and downloading an mp3 of an artist on the test you've never heard of.
Also also... just because you get a bad (or average) score, doesn't mean its a bad test. A lot of you took the 'Would you have been a Nazi' test, and didn't complain about your crummy score there.
