I think the preview is really different too. Ayu's in her stride in the verses here. The high pitch is done OK as well....after all what is an Ayu song without "dat squeak", right?
This song has a drama tie in right? I think if this is anything like how she'll sound in the bulk of the album songs we might be onto a winner. She sounds so good in the verses that I think the general public will like this song a lot
