I have agree with you though. I prefer to listen to "Hikari", rather than "Simple and Clean".

And the other post I made wasn't an example of superioty. It was just showing contrast. "Hikari" is more of a love song, while "Simple and Clean" is more of a 'I need my space' song. Even though "Simple and Clean" is better lyrically, such a song is kinda out of place in a game like Kingdom Hearts.
