She previews another part of the song.
Sounds like the ending to me:

She asks the rhetorical question if this isn't a song like she did them in the past.
She thinks, that the sexy Kumi from that time is one of the most important essences of her. Which is why she made this hot summer song to include it in the album.
Nice, playful lyrics.
