• Extract song, play-count, recent listening, artist, album, month, week, and year metrics.

• Generate CSV files plus summary.json.

Background

The extraction logic is based on local inspection of Musicolet backups. Backup internals are not an official public API and may change. The project aims to fail gracefully if a future Musicolet version changes its schema.
