^ that's a bit too short for me to judge
But I'm liking the dance, it's something different and unique. I like the chorus part and of course, the ring.
Nippon call was all I can remember from the song, so maybe that's a good thing
I like RihoxAyumin little dance. I thought they were having some dance battle again but it was just a pairing dance, not bad though.
Music wise, I still prefer What is Love? But this is a close second. I really hope Japanese public will like this song since it's the official support song now for the Winter Olympics.
