What do you do when you take one of my favorite songs of the year and translate it to the Japanese market? YOU HAVE TO MAKE IT FUCKING SHIT TO SUIT JAPAN.
The first problem I have with this version is the Japanese language. The original Korean version had some lines sung at a fast pace, and when you translate that into an extremely similar language with vocabulary words almost twice as long, hearing those rapid-fire lines in Japanese makes it sound like shit. It's not just this song in particular, it is every single Korean-to-Japanese song that has this problem, and songs with faster-sung lines such as AOA's Miniskirt exacerbates the problems.
I find the Japanese language to be a terrible match with genres such as pop and hiphop, though it is possible for Japanese in pop songs to sound good. For that to be the case, you have to start from the ground up and compose original Japanese songs. Being lazy and using a Korean track won't do. However, the problem with going with original Japanese songs is that 99% of Japanese pop composers suck gigantic dick. To make matters worse, J-pop has been using the same style of instrumentals for over 20 years now. Shit is stale as fuck.
On the MV side, the girls look hot (<3 Mina), but seeing as this is a Japanese MV, I'm surprised the girls were this provocative. Although Japan is the weird-porn capital of the world, the MVs are usually so disgustingly cute that even an Orange Caramel fan would throw up watching a Japanese idol MV. Therefore, I'm assuming that this was filmed in Korea because I don't see overly cute things in the MV nor any tentacle monsters defiling the members.
I would be more interested in seeing the band version of AOA working in Japan, as rock is a genre that Japan can actually do well (except for garbage bands like ONE OK ROCK). I would hate to see AOA abandon their Korean image just to suit the shitty-as-fuck toddler concepts that wotas in Japan love to fap to.
But in the end, I'm just disappointed that AOA debuted in Japan. Aside from SNSD and After School, every Korean girl group has shitty original Japanese songs. It's just the law of the land.
