The beat the song is built on is one bar, played through bars 1, 3 and 5, and 26 more places -- 31.2% 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 31 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 38 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 66 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 66, 77 and 88 BPM, and the gate at each one is 8 loops in a row with no wrong note and no wobble in the time.
