It says something about me that I enjoy the video even more now that I'm picturing the parents standing to the side, mocking their child for not having a piano accompaniment. I'm not sure what it says, but its probably not good.
Lots of the folks here in Korea can sing English songs. Damned if they know what the words mean, but they can sing them fairly clearly. This kid is what? 2 maybe? Yeah, he's probably been knocking back soju at the noraebang with his boss after work for at least a few months now.
