Well I haven't listened to the song completely yet. But I must say this.
The first time I've heard the song when I watched the raw video of the drama, I knew it was Arashi.
I didn't read about it anywhere yet so I was like, "I said so"... lol.
Apparently, I was late again. I'm always late with Arashi news. lol. Some friends just update me about them.
Point, Arashi has a distinct sound. Even though Jun's voice sucks, I know it's him. Ohno's voice is perfect and unique and so are the other member's voices.
