I built this after spending another Sunday afternoon fixing broken ID3 tags instead of actually mixing. 16,000 tracks. Half of them tagged wrong. Duplicates everywhere. Three different spellings of "Afrobeats."
So I built the tool I wished existed. One scan, everything sorted. No cloud, no subscription, no AI that thinks it knows your genre better than you do. Just clean metadata and smart crates, ready for the next gig.

Eight tools in one app. Zero bloat.
Point to your music folder. 16,000 tracks scanned in under a minute. Reads ID3, Vorbis, APE tags. Generates MD5 fingerprints for every file.
Catches junk URLs, watermarks, promo tags. Normalizes featuring credits. Batch-fix hundreds of issues in one click.
Detects by audio fingerprint, not filename. Compare side-by-side. Files never deleted.
Auto-fill genre, label, year. No API key needed — it just works.
Gemini suggests genres from metadata. Optional, works offline too.
Auto-generated crates by genre, moment (warmup/peak/close), or energy level. Export as M3U playlists. See your DJ identity at a glance with the visual library breakdown.
One-click ZIP backup. Restore in seconds. Music files never touched.
MP3, FLAC, WAV, AAC, AIFF, M4A, OGG. Universal compatibility.
One payment. Your library, forever organized.
30-day money-back guarantee. No questions asked.
Enter your code to download Library DJ.
macOS 12+ required. ~4MB download. Not sure? Apple menu > About This Mac.
If macOS says "Library DJ is damaged", open Terminal and run:
xattr -cr /Applications/Library\ DJ.app
Never. Library DJ only edits metadata tags. The duplicate finder removes database entries, not actual files.
Yes, 100%. Discogs lookup and AI genre suggestion are optional and the only features that need internet.
Tested with 16,000+. Virtual scrolling keeps the UI fast. SQLite with WAL mode under the hood.
No trial, but 30-day money-back guarantee. Doesn't work for you? Full refund, no questions.
Coming soon. Built with Tauri so Windows support is native. Mac first because that's what most DJs use.
Google Gemini suggests genres from track name and artist text. Audio files are never uploaded.
