The beat the song is built on is one bar, played through bars 53-76 and 85-156 -- 64% of every bar the kit plays. Learn that one and the song is very nearly finished.
It is played on snare, kick and hi-hat foot, counted in sixteenth notes. On its own it scores 35 out of 100 -- a fair first song -- and the thing that decides that is how much of it falls off the beat.
The whole song is 47 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 90 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 90, 105 and 120 BPM, and the gate at each one is 8 loops in a row with no wrong note and no wobble in the time.
