Import
Add audio — duplicates are skipped automatically (exact files by content hash; same recording flagged by ISRC).
Royalty-manager sync
Import the monthly drop: lossless WAVs from the shared Drive folder + authoritative metadata from the Google Sheet (the sheet is the source of truth — Identify is skipped; only diagnostics + tagging run, and album art is downloaded + stored). Load tabs to pick which sheet tab to read (defaults to the first). Preview = dry-run reconciliation. Sync now = download + import the new tracks.
Duplicate recordings
Tracks sharing an ISRC — likely the same recording imported more than once. The oldest is listed first.
