The beat the song is built on is one bar, played through bars 51-54, 57-60 and 63-66, and 17 more places -- 45% of every bar the kit plays. Learn that one and most of the song is already under your hands.
It is played on crash, hi-hat, snare and kick, counted in sixteenth notes. On its own it scores 79 out of 100 -- demanding -- and the thing that decides that is how many notes a second it asks for.
The whole song is 85 out of 100, so the beat is most of what the song asks for. Get it clean and the rest follows.
A part this hard is not learned by playing it slowly and hoping. The room opens it on its simplest reduction -- the timekeeper alone, at 91 BPM -- and adds the notes back over 5 rungs, each with a tempo to reach and a gate to pass before the next.
Tempo goes 91, 109, 128, 146 and 165 BPM, and the gate at each one is 8 loops in a row with no wrong note and no wobble in the time.
