Wow, what a disaster. I actually like this song in Korean, but this is the disaster I was predicting. First of all, the whole song sounds bad in Japanese, and it's not just their accent. The song just didn't transition well to Japanese.
Anyone else notice how awful the rapping was? I called it. Shit is hysterical. They get a .001/10 on my Verbal scale for rapping. Watch the end though, the girls going apeshit after Chansung takes off his shirt is almost as funny as the performance itself.
