The beat the song is built on is a 2-bar phrase, played through bars 27-38, 79-86 and 127-134 -- 17.7% of every bar the kit plays. This one moves around more than most: the beat is where to start, not the whole job.
It is played on crash, ride, snare, mid tom, floor tom and kick, counted in sixteenth notes. On its own it scores 43 out of 100 -- a fair first song -- and the thing that decides that is the independence between the hands and the feet.
The whole song is 68 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 104 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 104, 121 and 138 BPM, and the gate at each one is 8 loops in a row with no wrong note and no wobble in the time.
