You all exist on the internet, so you all know Psy from Gangnam style. You might love him, or hate him, or whatever. Regardless, you should watch this video, because it is impossible to not enjoy it/empathize with him.
This is from a recent show in Seoul, Korea. He's covering a song called 'Dream of Goose', which I assume is popular from another Korean artist? I don't know much about K-Pop, tbh. However, the real joy from this video is just watch the heart he has while singing, couple by the look on his face of "I can't believe I got here."
Just watch it. It's really worth it.
Also, after some digging, this seems to be the original version. It's also really beautiful.
