The beat the song is built on is one bar, played through bars 3, 31 and 61-63, and 5 more places -- 36.5% 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 54 out of 100 -- a step up -- and the thing that decides that is how many notes a second it asks for.
The whole song is 66 out of 100, so the beat is not the hard part: what costs you is everything around it, the joins and the fills.
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 75 BPM -- and adds the notes back over 4 rungs, each with a tempo to reach and a gate to pass before the next.
Tempo goes 75, 89, 102 and 116 BPM, and the gate at each one is 8 loops in a row with no wrong note and no wobble in the time.
