69 out of 100: demanding, mostly on how much of it falls off the beat.
snare through bars 1-34, ride through bars 35-36, hi-hat through bars 37-44, ride through bars 45-68, hi-hat through bars 69-84 and kick and crashes through bars 85-86, and 7 more changes after that.
The beat the song is built on is one bar, played through bars 1-31 and 33 -- 24.2% of every bar the kit plays. This one moves around more than most: the beat is where to start, not the whole job.

69 out of 100: demanding, mostly on how much of it falls off the beat. The beat itself is 23 out of 100; the rest of the number is everything around it.
