The beat the song is built on is one bar, played through bars 11-12, 15-16 and 19-20, and 8 more places -- 43.4% of every bar the kit plays. Learn that one and most of the song is already under your hands.
It is played on hi-hat, snare, mid tom, floor tom and hi-hat foot, counted in sixteenth notes. On its own it scores 69 out of 100 -- demanding -- and the thing that decides that is how many notes a second it asks for.
The whole song is 79 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 107 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 107, 127, 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.
