In this case, I see multiple parties resorting to pedantry over a legitimate point of discussion, reducing to mud slinging over semantics. The point stands.

What’s the point that stands? How do you justify the initial framing of “sounds over a beat”

I was pretty clear in what I said about music. I wasn't the one who made that remark, so I don't have anything to justify except my own statements.

The distinction is simple: music, as examined already during the times of Pythagoreans, invokes a soothing feeling of harmony, peace and belonging, while the mentioned "sounds with beat" (a non-technical term in this case) invoke body reactions like dizziness and anxiety.
