The beat the song is built on is one bar, played through bars 13-20, 33-40 and 53-64, and 1 more place -- 38.7% 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 76 out of 100 -- demanding -- and the thing that decides that is how many notes a second it asks for.
The whole song is 80 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 70 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 70, 85, 99, 114 and 128 BPM, and the gate at each one is 8 loops in a row with no wrong note and no wobble in the time.
PRACTISE THIS BEAT →A one-bar groove on crash, hi-hat, snare and kick, in 4/4 at 128 BPM, counted in sixteenth notes. It is written out above, and it covers 38.7% of the bars the kit plays.
Bars 13-20, 33-40, 53-64 and 71-78. The time is kept on the hi-hat to start with, and it changes 7 times over the song.
76 out of 100 on its own -- demanding. The song as a whole is 80 out of 100. Hard, and what makes it hard is the independence between the hands and the feet.
