Ayu's influence on other artists

[& + H]

This thread reminded me of that one guy who did almost all the hits from the 90's to now.

People always say oh this band is better than the other, when it's basically the same
dude who arranges and composes the music. Maybe most of the artist that have been
posted here are under the same record label or they have worked with the same persons who composes the music.

I find it cool, sorry if it's kind of off topic.
