Scan is slow on huge libraries.

Chromaprint fingerprinting is CPU-bound and runs on every track. A 50,000-track library takes 30–60 minutes on Apple Silicon. This is expected behaviour.

Key detection disagrees with Rekordbox.

CueRadar re-analyses from the audio stream, ignoring whatever Rekordbox previously wrote to the file. Tag-time analyses differ when libraries contain decade-old tags.
