Before I go all dramatic, I'll wait for the next day sales
This single does seem rushed, I wonder why... I thought that it's because of the rumored album and the contract ending soon, but if it's a compilation album... Maybe it's a compilation album with a new title track to promote
Also, I got the impression (I don't know, maybe it's only me) - that the public seems to be more interested in Step. People were teased with an awesome dance song and maybe Step outshined calm and simple Winter Magic. Seeing the response for Step in Japan I wished it was a double-track like Jumping - one version for Korea, the other one for Japan. But it seems that the choice for single songs was made some time ago, before the Step planning/concept <--- I'm just guessing here.
I did translate a few comments on Step from youtube (with google translation, so it wasn't the most accurate translation ever XD) and the fans wished in those commnents for a similar song in Japan. You know - catchy, with awesome choreo and an epic MV. Winter Magic is just too quiet compared to what was making the fandom go wild during those few last weeks.
But! Fear not. If the single sells consistently - all will be well after all. And if it doesn't - I guess experienced people are running this business and they'll know what to do for Kara's next release in Japan
