The beat the song is built on is a 2-bar phrase, played through bars 19-22, 27-34 and 44-63 -- 50% of every bar the kit plays. Learn that one and most of the song is already under your hands.
It is played on crash, ride, snare and kick, counted in sixteenth notes. On its own it scores 53 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 54 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 62 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 62, 73, 84 and 95 BPM, and the gate at each one is 8 loops in a row with no wrong note and no wobble in the time.
