If you have more than a few thousand tracks in Apple Music, you almost certainly have duplicates. iCloud sync issues, re-imports, and Apple Music's own Matched feature all create extra copies quietly over time. A 10,000-track library typically has 300–600 duplicate groups.
This guide covers two ways to find and remove duplicates in Apple Music on Mac: the built-in method and a dedicated app for larger libraries.
Contents
The Music app on Mac includes a basic duplicate finder. Here's how to use it:
File > Library > Show Duplicate Items.File > Library and you'll see Show Exact Duplicate Items instead. This is stricter — it only matches tracks with identical title, artist, album, and duration. Fewer false positives.To exit the duplicate view, click Done at the top of the window.
The built-in finder works for simple cases but has significant limitations for anyone with a large library:
| Feature | Built-in | MusicLibrarian |
|---|---|---|
| Exact duplicate detection | ✓ | ✓ |
| Similar track detection (minor title differences) | ✗ | ✓ |
| Quality variant detection (same track, different bitrate) | ✗ | ✓ |
| ISRC audio fingerprint matching | ✗ | ✓ |
| Side-by-side bitrate / format comparison | ✗ | ✓ |
| Auto-select best quality version | ✗ | ✓ |
| Transfer ratings before deletion | ✗ | ✓ |
| Batch delete | ✗ | ✓ |
The built-in tool also misses duplicates where titles differ slightly — for example "Bohemian Rhapsody (Remastered)" and "Bohemian Rhapsody" are the same track but won't be grouped together by Apple's method.
MusicLibrarian is a free Mac app that scans your entire Apple Music library and groups duplicates by exact match, similarity, and quality variant. It's built for people with 5,000+ tracks who need a thorough clean.
Open MusicLibrarian and click the Duplicates tab. Select your source (full library or a specific playlist) and click Scan. The scan runs in seconds even for large libraries.
Click Identify ISRC to run audio fingerprint matching. ISRC codes are unique identifiers assigned to each recording. Two tracks with the same ISRC are definitely the same recording — even if their tags differ. This step rules out false positives like studio vs. live versions of the same song.
Expand any duplicate group to see a side-by-side comparison: bitrate, file format, file size, play count, and rating. Click Keep Best to automatically select the highest-quality version, or manually mark your keeper.
If the track you're removing has a star rating, use the transfer button to copy it to the keeper first. Then click Delete Flagged Tracks to remove all non-keepers in one batch.
MusicLibrarian scans your full library at no cost. Up to 10 fix actions free — no account required.

In the Music app, click Songs in the sidebar, then choose File > Library > Show Duplicate Items. Hold Option for exact-only matching. For more advanced detection, use MusicLibrarian.
Yes. It's under File > Library > Show Duplicate Items in the Songs view. It detects tracks with matching title and artist, but misses similar tracks, quality variants, and doesn't support batch deletion.
Common causes: iCloud sync creating double entries, importing files you already had in your library, Apple Music re-downloading tracks from the catalog, or the Matched feature pairing your upload with a catalog copy and keeping both. Libraries with 5,000+ tracks typically accumulate hundreds of duplicate groups over time.
Yes, as long as you check which copy to keep (prefer higher bitrate or lossless format) and transfer any ratings from the track you're deleting. MusicLibrarian shows both copies side by side so you always make an informed choice.
MusicLibrarian is purpose-built for Apple Music duplicate management on Mac. It uses ISRC audio fingerprinting to confirm true duplicates, shows format and bitrate side by side, transfers ratings automatically, and batch-deletes in one click. Free to scan.
