Cross-platform DJ library manager

One tool for every DJ library

Rekordbox, Serato, VirtualDJ — read natively, written correctly. Windows and macOS.

The problem

Most DJs end up with a stack of tiny utilities: one to dedupe, one to migrate, one to fix missing tracks — each with its own UI and its own limitations. And almost all of them require XML export/import chains that lose data.

How Music Library Doctor does it

1 Install Music Library Doctor (Windows 10+ or macOS, Apple Silicon or Intel).
2 MLD auto-detects Rekordbox, Serato, and VirtualDJ libraries on the machine.
3 Use it to transfer playlists between any of the three, either direction.
4 Clean up with the built-in missing-track repair and duplicate finder.
5 Free tier covers viewing and detection. Pro ($4.99/mo) and Lifetime ($49) unlock batch fix and transfer.

Supported today

Rekordbox · Serato DJ · VirtualDJ (incl. Favorite Folders) on Windows 10+ and macOS (Apple Silicon + Intel).

Why native integration matters

We read master.db (Rekordbox), _Serato_ crate files (Serato), and database.xml (VirtualDJ) directly — then write back to each app's native format. No XML middleman, no lossy conversion, no rebuilt hierarchy.
