Summary

Previously, Spotify local files could end up in queues, including shuffle queues, which would cause the metadata resolver to simply "guess" the song, which would generally be incorrect. This solves this issue.

Behavior Notes

parseGqlTrack now sets SpotifyTrack.isLocal, meaning that they're excluded from both the playlist listing and queues when playing a playlist. Local files in a Spotify playlist should no longer show in the track list nor should they appear in the queue when the playlist is played.

Privacy / Security Checklist

• No secrets, keys, tokens, keystores, signing files, private certificates, or local machine paths are committed.
• Logs do not expose access tokens, cookies, auth headers, user identifiers, listening history, or local file paths.
• New network calls are justified by the feature and use existing client, proxy, timeout, and error-handling patterns.
• User data remains local unless the PR explicitly documents the integration and consent path.

Verification

• Android Studio sync: Successful Gradle sync and compilation
• Manual device/emulator verification: Local files in Spotify playlists no longer appear in either the tracklist nor in the queue.
• UI screenshot/recording attached: N/A (no changes to UI)
• Accessibility or touch-target review: N/A (no changes to UI)
• Regression areas checked: Regular tracks parse correctly, while local files are excluded from Spotify playlists as intended.
• CI expectation: Successful build with no errors.

Reviewer Focus

Spotify GQL parsing (parseGQLTrack), verify that local files are excluded from Spotify tracklists and queues and confirm that normal tracks work fine.

Release Notes

Excluded Spotify local files from Spotify playlists.
