The beat the song is built on is one bar, played through bars 21-35, 37-42 and 45-74, and 1 more place -- 79.8% 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 45 out of 100 -- a step up -- and the thing that decides that is the independence between the hands and the feet.
The whole song is 52 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 90 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 90, 105 and 120 BPM, and the gate at each one is 8 loops in a row with no wrong note and no wobble in the time.
