Local Music Organizer for Mac

Clean up large local Music.app libraries safely.

Local Music Organizer is an offline-first Mac utility for people who keep real local Music.app libraries: playlists, files, artwork, tags, duplicates, audio quality checks, smart shuffle, and repair workflows without cloud lock-in.

Safety-first by design

The app scans first, shows results, exports reports, and only applies changes when you explicitly choose an action. It does not physically delete audio files.

  • Review result lists before applying changes.
  • Export reports for backup and inspection.
  • Undo is available for supported app actions, but it is not a substitute for a real Music library backup.
  • Physical audio file deletion is intentionally not implemented.

Smart Shuffle Builder

Build shuffled playlist copies that feel more natural than simple random order. Smart Shuffle is designed to reduce repeated artist clusters, album blocks, and predictable local patterns.

  • Create shuffled copies without damaging the source playlist.
  • Spread artists and albums more evenly across the playlist.
  • Avoid obvious back-to-back repetitions where possible.
  • Useful for large genre, mood, decade, and mixed collection playlists.
  • Works with local Music.app playlists through safe playlist-copy workflows.

Library Dashboard

A read-only overview for large local libraries. It scans Music.app records and file information, then groups practical cleanup problems into clear filters.

  • Empty artist fields
  • Low bitrate MP3/AAC tracks
  • Missing artwork
  • Missing local files
  • Long duration outliers
  • Export current filtered issue lists

Audio quality inspection

Inspect technical audio details to understand what is actually in your library, not just what Music.app displays.

  • Codec and container information
  • Bitrate, sample rate, channel count, and duration
  • Lossless/lossy quality clues
  • Bit depth where meaningful
  • MP3/AAC lossy tracks display bit depth as not applicable
  • Spectrogram and waveform-style inspection tools where available

Duplicate cleanup tools

Find repeated entries and duplicate library records without touching physical files.

  • Duplicate entries inside one playlist
  • Duplicate Music library records pointing to the same local file
  • Quality duplicate candidates across different physical files
  • Verified cleanup workflow for exact duplicate records
  • Recovery playlist support for safer review

Playlist tools

Understand where tracks are used and how playlists overlap.

  • Library playlist map for repeated tracks
  • Playlist Compare: shared and repeated tracks between two playlists
  • Track Usage search by artist, title, path, filename, or persistent ID
  • Find local files on disk for suspicious or recovered tracks

Artwork and health checks

Find common library problems that are hard to spot manually in a large collection.

  • Tracks with no Music.app artwork
  • Missing file links
  • Suspicious local path problems
  • Finder metadata and permission checks for local audio files
  • Network Safe mode for NAS, SMB, iCloud, and external-drive libraries

Tag editing from results

Edit visible Music.app metadata directly from result rows.

  • Title, artist, album, album artist
  • Composer and genre
  • Year, track number, disc number, and comments
  • Dashboard issue counters update after supported tag edits

Tag editing changes the Music.app record through AppleScript. It does not rewrite the physical audio file.

Repair / Convert

Convert many common, old-school, and audiophile audio formats into Music.app-compatible output files. This is designed for libraries that contain formats Music.app may not import or play reliably.

  • Convert FLAC, WAV, AIFF, OGG/Opus/WebM, APE, WV/WVC, TAK+CUE, OFR/OFS, MPC, TTA, SHN, ATRAC, tracker modules, game audio, AC3/EAC3/DTS, CUE, M3U/M3U8/PLS and other supported inputs when the required tools are installed.
  • Output profiles include Music.app-friendly formats such as Apple Lossless ALAC M4A, AAC, MP3, AIFF, and WAV-style workflows.
  • CUE album workflows are supported for splitting or converting album images where helper tools can process them.
  • Optional repair helpers can install or check external command-line tools such as FFmpeg/LAME and old-school codec helpers.
  • Original source files are not overwritten.
  • Converted files are written to a chosen output folder for review before import.

File Maintenance

Focused local file maintenance for audio folders.

  • Check audio file permissions
  • Normalize common permission problems
  • Scan Finder metadata
  • Remove Finder metadata from local audio files
  • Designed for local folders, external drives, and large media trees

Export and diagnostics

Keep reports outside the app for review, support, and repeatable cleanup.

  • Export dashboard logs
  • Save current filtered issue lists
  • Open log folder from the app
  • Export diagnostics for troubleshooting
  • Progress counters during long scans

Offline-first

Built for local Music.app libraries. No cloud music subscription is required, and online-library tools are hidden from the first commercial build.

Large-library ready

Fast, Standard, and Deep scan modes help balance detail and speed. Network Safe mode avoids thousands of slow file-stat calls on NAS, SMB, iCloud, and external drives.

Beta status

Local Music Organizer is currently in private beta. Public downloads will be added after additional testing, code signing, notarization, and release documentation.

Requirements

  • macOS 14 Sonoma or later
  • Music.app local library
  • Apple Silicon and Intel Universal build

What it does not do

  • It does not physically delete audio files.

  • It does not upload your music library.
  • It does not replace a proper backup.
  • It does not promise that every rare audio format can be converted without the required external tools.
