Can you imagine Ayu singing this song?
 

If Ayu was a TK face I imagine this is the sort of stuff she would have debuted with.

Some parts of that song, yeah, I could see Ayu singing that. Other parts not so much, doesn't seem like her style at all.

What's TK?

^ Who is TK you mean. :p

Tetsuya Komuro, prolific 90s producer/composer/artist/everything for Avex in the 90s. In globe, but also worked on early Namie Amuro, early hitomi... a multitude of artists who were the TK family. You must be familiar with his sound, that 90s dance sound in Jpop. Google him, he's THE guy in 90s Jpop. One of the people, to put it, who you have to know.

He worked on most of Ayu's Love Songs (hence it's throwback sound), aside from that their only song together is A song is born.

Oh! Ok, haha, I recognize the name Tetsuya Komuro, just not TK. :D
