Library diagnostics
Your DJ library, scored 0–100
A single health score — missing tracks, duplicates, broken links, scattered folders — with one-click actions to push it up. Works across Rekordbox, Serato, and VirtualDJ.
What is
What is a music library health score?
A single 0–100 number that summarizes your library's state across missing files, duplicates, broken paths, folder scatter, and audio quality.
Why is
Why is my Rekordbox library missing tracks?
The red icon almost always means the file path changed. The track is still on disk — Rekordbox just lost the breadcrumb. Bulk repair takes minutes.
Why is
Why are my Serato hot cues missing after transfer?
Serato stores hot cues inside the audio file itself (ID3 tags) AND in the Serato database. If only the database moved, the cues look gone.
Why is
Why does VirtualDJ say my database is corrupt?
Almost always a partial write to database.xml — VirtualDJ was closed mid-save or the disk hiccupped. MLD diagnoses and restores from backups.
