The beat the song is built on is one bar, played through bars 1-11, 13-21 and 31-43, and 1 more place -- 42.5% of every bar the kit plays. Learn that one and most of the song is already under your hands.
It is played on hi-hat, snare and kick, counted in sixteenth notes. On its own it scores 55 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 63 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 64 BPM, and adds the notes back a rung at a time -- 4 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 64, 76, 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.
