The beat the song is built on is a 2-bar phrase, played through bars 54-77 and 102-125 -- 38.1% of every bar the kit plays. Learn that one and most of the song is already under your hands.
It is played on crash, ride, snare and kick, counted in thirty-second notes. On its own it scores 50 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 71 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 71 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 71, 83 and 95 BPM, and the gate at each one is 8 loops in a row with no wrong note and no wobble in the time.
