1) It's based on their play points and chart performances.
2) "Polyrhythm" is the 5th biggest song on Delta 40 ever. It spent 5 weeks @ #1 three years ago. "Love the World" and "Polyrhythm", both by Perfume, are the only japanese songs to ever reach #1 on Delta 40. It's currently tied with Nicola Roberts' "Beat of My Drum" which also achieved almost 3 million points to date although it spent 1 week at #1 more than "Polyrhythm" did.
