Problem

A music-streaming platform emits a play event every time someone starts, pauses, or skips a track, and three teams read that same feed: recommendations wants what a listener is playing reflected in their home feed within a minute, royalty accounting must count each qualifying play (30 seconds or more of listening) exactly once because payouts to rights-holders can't be clawed back, and product analytics reports daily engagement the next morning. Design the platform that ingests the play stream once and serves all three from it at their own freshness and correctness needs.
