Great!
I really loved the intro, without it I wouldn't have listened to the song. It builds up the song very good.
And I really like that it never goes too loud or too much of everything. It stays perfectly balanced. I like how you go up and down in the song. Like in the beginning the song goes really slow and then it kicks off but not all the way. It's like that through the whole song until the end where it really goes off like a rocket :P.
Perfect intro as i've said. Great song!
