The beat the song is built on is one bar, played through bars 17-25, 27-38 and 58-66, and 19 more places -- 48.2% of every bar the kit plays. Learn that one and most of the song is already under your hands.
It is played on crash, snare and kick, counted in thirty-second notes. On its own it scores 20 out of 100 -- straightforward -- and the thing that decides that is how fine the subdivision is.
The whole song is 69 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 119 BPM -- and adds the notes back over 3 rungs, each with a tempo to reach and a gate to pass before the next.
Tempo goes 119, 138 and 158 BPM, and the gate at each one is 8 loops in a row with no wrong note and no wobble in the time.

Bars 17-25, 27-38, 58-66 and 68-71, and 18 more places. The time is kept on the silence to start with, and it changes 15 times over the song.
20 out of 100 on its own -- straightforward. The song as a whole is 69 out of 100: demanding, mostly on how fine the subdivision is.
