I don't know.
Apparently one year ago, when I signed up for my itunes/Apple store account, I filled that in as my security question.
When I forgot my password (yes yes I am that type) and that question popped up, I stared at it in horror for a full two minutes, taken aback by the depths of my idiocy - I mean, seriously, what is my favourite song? That changes every 24 hours!
Yes, of course I spent the better part of the next hour desperately trying to remember.
I tried all of these...
Beyond the sea
Fly me to the moon
Symphony No 9
Walking on sunshine
I can see clearly now
... to no avail. Apple rejected me every time.
Why why WHY did I fill that in as my security question? Which alien descended from Mars, took over control of my body and made me do something as colossally silly as that?
