Fix Corrupt OS X Music Library

Of course. Dealing with a messy or problematic music library is a common issue on macOS. The “best” app depends on the specific problem you’re facing.

Here’s a breakdown of the top apps and tools to fix, clean, and organize your macOS music library, categorized by their primary function.

1. The Built-In Solution: Music App (macOS)

Before you try third-party apps, always try the built-in tools first. They can solve many common issues.

Best for: Basic metadata fixes, album artwork, and library corruption.

• How to use it:
  • Get Album Artwork: Select one or more songs/albums, then right-click and choose Get Album Artwork. (Requires being signed into your Apple ID account that purchased the music).
  • Edit Metadata Manually: Select a song, press Cmd + I (or right-click > Get Info). Here you can edit song titles, artists, albums, genres, etc., for single tracks or in batches.
  • Consolidate Library: This gathers all your music files from various locations on your drive and copies them into the default Music/Media/Music folder. Go to Music > Settings > Files and check Copy files to Music Media folder when adding to library. Then, to clean up, you can use File > Library > Organize Library… and check Consolidate files.
  • Reset the Library Database: If your library is corrupted (songs skipping, duplicates appearing out of nowhere, play counts not updating), you can try resetting the library database. Quit Music.app, then go to ~/Music/ and rename Music Library.musiclibrary to Music Library Old.musiclibrary. Reopen Music.app; it will create a fresh, empty library. You can then use File > Import… to re-import your music files from their folder (hopefully after you’ve Consolidated them).
