Aligning Lock Screen Controls and Track Loading to the Same State Flow

When the screen is off, users rely entirely on the lock screen controls and track metadata display. Any mismatch between that surface and the actual playback state — paused on the lock screen while audio continues, or a track transition not reflected in the display — directly undermines playback reliability.

The goal was to consolidate the control path so that lock screen remote controls and track loading operate within the same state flow. The audio session, metadata display, and playback surface were integrated to eliminate independent operation, and the sequencing between track load events and remote control inputs was adjusted to prevent state overwrites. Track metadata and recommendation display logic were also unified under a consistent rendering standard.

Ongoing work continues to reduce interference between audio, video, mount state, and display metadata in the playback path. The target is consistent playback state and control responsiveness that persists after the screen is turned off.
