The beat the song is built on is a 2-bar phrase, played through bars 13-27, 29-35 and 37-44, and 3 more places -- 63.4% of every bar the kit plays. Learn that one and the song is very nearly finished.
It is played on crash, hi-hat, snare and kick, counted in sixteenth notes. On its own it scores 45 out of 100 -- a step up -- and the thing that decides that is the independence between the hands and the feet.
The whole song is 46 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 107 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 107, 125 and 143 BPM, and the gate at each one is 8 loops in a row with no wrong note and no wobble in the time.
