Why am I finding this shit in Korea? I was about to fall asleep last night when I saw this video on TV. I couldn't sleep for hours. Seriously, if I feel down or sad, I just watch this a couple times and I'm so pumped I could run through a brick wall. There better be a channel in the US devoted to this music video. The 4th movie gets 4 stars before I see it just because of this song. I just headbutted the guy behind the counter at the pc room.
