Are you Tone Deaf?

Here's a really difficult online test that will tell you.

Note that the site is currently down because it's on digg.com, and millions of enthusiastic music lovers are banging away at the site trying to find out how tone deaf they really are. So you might need to try again tomorrow when the Digg Effect dies down.

I scored 86.1%. 90% is supposed to be "world-class music abilities", whatever that means, so I'm not sure how accurate this thing is. Suspectu! Anyway, an interesting way to waste 15 minutes.
