The beat the song is built on is one bar, played through bars 4, 6-8 and 12-14, and 23 more places -- 50.6% 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 67 out of 100 -- demanding -- and the thing that decides that is how much of it falls off the beat.
The whole song is 77 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 73 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 73, 86, 99 and 112 BPM, and the gate at each one is 8 loops in a row with no wrong note and no wobble in the time.
