Summary

A critical fix for engagement metrics ensuring that partial listens, skips, and background plays are accurately recorded. This update increases data capture from ~10% to over 90% of all playback activity.

​
What’s New

  • Partial Listen Tracking: The system now captures duration data for all listens over 10 seconds, even if the track isn’t finished.
  • Reliable Data Delivery: Implemented navigator.sendBeacon to guarantee data is sent even when a user closes the tab or navigates away.
  • Guest Tracking: Anonymous plays are now properly recorded and visible in “Top Listeners” as aggregated guest traffic.
  • Entity Scoping: Fixed a bug where track and album analytics were showing global artist data. Now, insights are strictly scoped to the specific entity.

​
Why It Matters

  • Accurate Reporting: Producers now see the true engagement on their tracks, not just full completions.
  • Better Insights: Understanding drop-off points (via completion rate) helps artists improve their content.
  • Data Integrity: Eliminates the “Not Available” state for engagement metrics on most tracks.

​
Technical Details

  • Event Triggers: Duration is now sent on pause, seek, track_change, and page_unload.
  • Threshold: A 10-second minimum threshold filters out accidental clicks.
  • Backend: TrackPlaysController now accepts and aggregates partial duration updates.
