What is that rhythm?

I suck with the technicalities of music, what all the beats are called and whatever. But there's something about the rhythm in Masafumi Takada's earlier works that feels really special to me. Something about them that appeals to me a lot.

I have no idea what the term for them, but if you listen to:
- Without Chewing Gum Syrup
- Deep Shot of Midnight Sun (Both from Flower, Sun and Rain)
- The Silver Case (The title theme)

... hear that rhythm? That fast one that you could drum easily with your fingers? That one.

ALSO, HAPPY BIRTHDAY HARU.
