00:21:995 (4,5) - i don't really think this is necessary, u mapped this the same as 00:22:366 (1,2,1,2,1,2,1,2) - but actually i think it's better to change it, it's not the same sound ://// it will give more contrast
they are all stacked like that because of the vocals, spacing is different for the later stacks because of the intensity change from the new instrument. But the vocals pretty much stays the same so changing the representation for the vocals would seem incorrect
