Your smart playlists might be broken right now. Apple Music quietly downgrades tracks to compressed audio and spreads phantom ratings across your library. MusicLibrarian finds and fixes everything — duplicates, broken ratings, missing lossless — in one click.
From scan to fix in under 30 seconds.
Every way your Apple Music library can break, MusicLibrarian can fix.
Duplicates
MusicLibrarian finds exact copies, near-matches, and quality variants hiding in your library. Its smart auto-selection keeps the best version of every track — highest bitrate, best metadata, original artwork. Delete the rest in one click.
iCloud Health
Unavailable songs. DRM-locked files. Matched tracks that silently degraded to lower quality. MusicLibrarian scans your entire iCloud Music Library and surfaces every problem, categorized by severity — so you know exactly what to fix first.
Lossless
Thousands of your Apple Music tracks may still be streaming in compressed AAC when lossless versions exist. MusicLibrarian identifies every upgradeable track and batch-processes your entire library to full ALAC quality. No manual searching. No track-by-track work.
Inherited “grey” ratings silently break your smart playlists. Find them all and reset them so your ratings reflect your actual taste.
Compare International Standard Recording Codes to tell real duplicates from different recordings of the same song. Studio version vs. live version? Now you'll know.
When metadata lies, audio doesn't. MusicLibrarian identifies the actual song in each file and flags mismatches — corrupted tags, wrong titles, swapped tracks.
Find missing and low-resolution artwork across your library. Pull high-res covers from the Apple Music catalog and apply them in one click.
Apple Music doesn’t tell you. We do.
When you re-download songs, Apple Music may replace your lossless files with compressed AAC versions. You won’t notice until you check.
Same song, slightly different metadata. Apple Music can’t see them. Your playlists play the same track twice — or skip the version you actually rated.
Rate 2 songs on an album, and Apple silently gives 5 stars to every other track. Your “Top Rated” playlist fills with songs you never chose.
MusicLibrarian reads your entire Apple Music library using native macOS frameworks. No uploads. No cloud sync. Every byte stays on your Mac.
Duplicates, broken ratings, quality downgrades, iCloud failures, missing artwork — everything is surfaced in a clean dashboard, sorted by severity.
Delete duplicates, reset ratings, upgrade to lossless, repair artwork — in bulk, with one click. Your ratings and playlists are preserved through every operation.
When you rate a few songs on an album, Apple Music can automatically give every other song on that album the same rating — without telling you. Your "5-star" smart playlists? Probably full of songs you never actually rated.
MusicLibrarian detects these inherited ratings and lets you fix them.
The only all-in-one solution for Apple Music on Mac.
