I don't know. I really don't. They're both cute songs, they have the same tempo and there's the title too. (BTW, does it sound like a bad pun?)

Songs used:
● Suteki Hoshi no Sanpo wa Suteki (from "Katamari Damacy") w/ pitch -1
● Renai Circulation (from "Bakemonogatari")

It's a draft because I'm still trying some different combinations.
