Useful listening criteria for generated accompaniment

I am making a practice track for a dance class with spoken counts over generated instrumental backing. There is an audible buzz in the introduction near the cue for the first movement. The recording is intended for learning a sequence, with clear timing as the main requirement. I encountered remove suno artifacts while researching the buzz, and I want to evaluate any processing against that practical requirement. Before testing a processed copy, I want to define what would actually make it more useful in class. Should the comparison include the spoken introduction and an entire phrase at normal practice volume? I can keep the spoken layer identical so the backing track is the only part that changes. My listening notes would cover rhythmic attacks and the clarity of the downbeat alongside the unwanted texture. Which timing change would make you reject a processed version even if its background sounded cleaner?
