The problem

The Windows music library tooling landscape is broader than Mac's but similarly fragmented: foobar2000 for playback and tag cleanup, MediaMonkey for library management, dupeGuru-Windows for filename dedupe, Mp3tag for batch tagging, Spek for spectrum analysis, JRiver Media Center for audiophile playback. Each strong at its narrow scope; none combines library-wide FFT quality scoring + acoustic fingerprint dedup + folder consolidation + a single Library Health Score.

How Music Library Doctor does it

  1. 1 Pick your daily-driver. foobar2000 + Mp3tag for power users; MediaMonkey for managed-library workflow; JRiver for audiophile playback. All three are decades-mature.
  2. 2 Add MLD for the audit layer. FFT quality scoring exposes fake-320s and fake-FLACs that none of the above catch. Acoustic fingerprint dedup catches cross-format duplicates filename matchers miss.
  3. 3 Keep your daily-driver. MLD doesn't replace foobar2000 / MediaMonkey / Mp3tag — those tools own playback, tagging, and metadata, and MLD doesn't touch those layers.
  4. 4 Run MLD periodically. Yearly audits are enough for most collections. The Library Health Score makes the cadence visible — last year vs this year, what got better or worse.
  5. 5 Cross-platform note: results travel between Mac and Windows. If you switch machines, MLD on either OS reads the same files and produces the same audit.

Why native integration matters

Sharp tools layered beats one monolith. foobar2000 for playback, Mp3tag for tag work, dupeGuru-Windows for filename cleanup, MLD for the audit layer — each best-in-class for its narrow scope. MLD owns the FFT-based quality scoring and acoustic fingerprint duplicate detection: the analyses that require actually reading audio content, which the other tools skip because their scope is elsewhere. $19–49 lifetime is a small line item against the cost of a serious audio rig.

Frequently asked questions

Does MLD replace MediaMonkey or JRiver?

No. Those are playback + library management tools. MLD audits the files those tools play. Different scope, different layer.

Does MLD run on Windows 10 ARM?

Windows 10/11 on x64 is supported. ARM Windows (Snapdragon laptops) is on the roadmap.

Can I use MLD alongside Mp3tag?

Yes — they don't overlap. Mp3tag edits tags; MLD audits audio content. Run them sequentially on the same files.

Is there a free tier?

Yes. Full Library Health Score, full scans, and detection are free forever. Pro adds bulk fix actions and Smart Upgrade. $19 lifetime founder price for the first 100 users; $49 lifetime regular.

Get your library in shape in minutes

Free tier covers detection and viewing. Lifetime access is $49 — $19 for the first 100 DJs.
