LOL, I'm such a newbie, my first Ayu's PV was Mirrorcle World in 2008. Before that moment I didn't like Ayumi at all, but despite that fact I couldn't stop listening to randomly downloaded talkin' 2 myself and Decision, even though I had a headache in 5 minutes of listening
Then I accidentally saw a Mirrorcle World PV in news line at jpopasia and was intrigued just by the title
Watched it and went through the deep catharsis. That's how I was converted to the admiration for Ayumi Hamasaki
