The beat the song is built on is one bar, played through bars 63-83 and 112-118 -- 32.9% of every bar the kit plays. That is the spine of it; everything else is what happens around it.
It is played on hi-hat, snare and kick, counted in sixteenth notes. On its own it scores 40 out of 100 -- a fair first song -- and the thing that decides that is the independence between the hands and the feet.
The whole song is 35 out of 100, so the beat is most of what the song asks for. Get it clean and the rest follows.
The room opens this beat on its simplest reduction, at 128 BPM, and adds the notes back a rung at a time -- 3 of them. Nothing is a matter of opinion: each rung has a tempo to reach and a gate to pass before the next one.
Tempo goes 128, 149 and 170 BPM, and the gate at each one is 8 loops in a row with no wrong note and no wobble in the time.
