What exactly counts as a listen? That's the problem. A stream is a clear, countable event; a listen is a fuzzy judgment call. Is it 30 seconds, the whole song, or a loop on mute? Once platforms pay per listen, they invite gaming, disputes, and invasive tracking, and they punish casual discovery. If someone samples ten new artists but only fully listens to one, per-listen shrinks the payout pool for everyone else. I'll take per-stream: it's measurable, scalable, and harder to rig. Fairness needs clear rules, not a vibe.
