I usually don't judge previews but.. omg.
Ayu's voice sounded so low at the beginning, like when I'm singing at karaoke
. And during raps or whatever they are, the music goes too much fast so she sound like in hurry. Her vocals sounds quite good but the arrangement it's so cheap.
If she will gonna include this cover song in her next album, I hope it will be a bonus track or a ghost-track at least.
As I said I don't usually judge previews so early
but I don't like what I heard. I'm still looking forward the full song though.
