People seem to like this version more than the other versions because you can see "Y" in this MV (the girl playing the drums). Since she is a half-angel, she will only play the drums. Not sing or dance, and because people like the whole idea of them being a band, they feel like they should stick to that idea. And I kind of agree. they should stick to this, because there aren't so many KPOP-bands out there. They got attract a whole other audience which vould benefit them.
