Age requirement with iTunes...?

So, I'm having a problem with iTunes. I have an iPod, but I haven't bothered getting Genius on it until now. So, I decided that I'd turn on Genius, but it says I have to create an iTunes account. So, I start creating it, I put in the username, password, my date of birth. I happen to be 20 years old and I put my date of birth in that proves this, and then it tells me that I haven't met the minimum age requirement. I go back to see what the minimum age requirement actually is and I see that is, in fact, 13. I have not lied about my age, I am actually 20. It's on my passport, my credit card, my ATM cards So, basically my question is, what the f*ck is up with iTunes?
