The beat the song is built on is one bar, played through bars 31-43, 53-55 and 59-63, and 3 more places -- 58.9% of every bar the kit plays. Learn that one and most of the song is already under your hands.
It is played on the kick, counted in thirty-second notes. On its own it scores 0 out of 100 -- straightforward -- and the thing that decides that is how fine the subdivision is.
The whole song is 41 out of 100, so the beat is not the hard part: what costs you is everything around it, the joins and the fills.
The room opens this beat on its simplest reduction, at 75 BPM, and adds the notes back a rung at a time -- 3 of them. Nothing is a matter of opinion: each rung has a tempo to reach and a gate to pass before the next one.
Tempo goes 75, 88 and 100 BPM, and the gate at each one is 8 loops in a row with no wrong note and no wobble in the time.
