[Koda Kumi] Lead single for each Koda Kumi album?

[RPGames]

I wonder what you guys feel is the lead single for each Kumi album?

In western music artists' albums always (or usually) have one single before the album release, which really leads the album, and then a few singles afterwards. e.g. Womanizer and Circus album, Hung Up and Confessions on a Dance Floor album, Girlfriend and The Best Damn Thing album, etc.

For me it's:

TRICK - TABOO
Kingdom - FREAKY (though BUT and LAST ANGEL are good candidates too @_@)
Black Cherry - 夢のうた (or WON'T BE LONG?)
BEST -second session- - you (obviously lol)
secret - キューティーハニー

I'm not sure about the ones before that. ^^
