The beat the song is built on is one bar, played through bars 5-12, 14-16 and 21-32, and 3 more places -- 77.9% of every bar the kit plays. Learn that one and the song is very nearly finished.
It is played on hi-hat, snare and kick, counted in sixteenth notes. On its own it scores 48 out of 100 -- a step up -- and the thing that decides that is how much of it falls off the beat.
The whole song is 55 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 74 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 74, 87 and 99 BPM, and the gate at each one is 8 loops in a row with no wrong note and no wobble in the time.
