When we mixed the song, we already know what it needs. Light Mastering is that final stage — setting loudness for streaming platforms, tightening the low end, and making sure the track holds up next to anything else in a playlist.
This tier is only available for songs mixed here, and that's not an upsell tactic. Mastering someone else's mix means evaluating it from scratch, and that's genuinely more work — which is what Full Mastering covers.
