The beat the song is built on is one bar, played through bars 5-23, 25-31 and 33-59, and 3 more places -- 94.6% of every bar the kit plays. Learn that one and the song is very nearly finished.
It is played on ride, snare and kick, counted in sixteenth notes. On its own it scores 19 out of 100 -- straightforward -- and the thing that decides that is the speed of the hand keeping time.
The whole song is 27 out of 100, so the beat is most of what the song asks for. Get it clean and the rest follows.
The room opens this beat on its simplest reduction, at 126 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 126, 147 and 168 BPM, and the gate at each one is 8 loops in a row with no wrong note and no wobble in the time.
