The beat the song is built on is one bar, played through bars 13-32 and 41-60 -- 58.8% of every bar the kit plays. Learn that one and most of the song is already under your hands.
It is played on ride, hi-hat, snare, high tom, kick and hi-hat foot, counted in thirty-second notes. On its own it scores 78 out of 100 -- demanding -- and the thing that decides that is how many notes a second it asks for.
The whole song is 89 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 47 BPM -- and adds the notes back over 5 rungs, each with a tempo to reach and a gate to pass before the next.
Tempo goes 47, 56, 66, 75 and 85 BPM, and the gate at each one is 8 loops in a row with no wrong note and no wobble in the time.
