DupeSnoop

Tired of seeing multiple versions of the same song cluttering your Apple Music library? DupeSnoop helps you identify and manage duplicate tracks, special editions, remasters, and variations - making it easy to keep only the versions you want.
Key Features:
* Smart Duplicate Detection: Automatically identifies duplicate songs, even when they have different album names or edition markers (Deluxe, Remastered, Live, etc.)
* Visualize Duplicate Groups: View all versions of a song grouped to easily compare and choose your preferred version
* Queue-Based Workflow: Select unwanted songs and add them to a removal queue for batch processing from within Apple Music
* Favorite Integration: Favorite your preferred versions right from the app
* Advanced Filtering: Filter your library by duplicates, favorites, explicit/clean content, compilations, soundtracks, greatest hits albums, and special editions
* Hide False Positives: Hide duplicate groups you want to keep, which automatically reappear if new versions are added
* Playlist Integration: View which playlists are common amongst the duplicate songs and match them to keeps before you process
* Catalog Search: Search Apple Music's catalog to find alternate versions and compare release dates
* Detailed Song Information: View comprehensive metadata including release dates, track numbers, play counts, and more
* Sorting Options: Sort your library by title, artist, or album in ascending or descending order

Free vs "Deluxe Special Edition"
* Free version is 100% functional to find and remove duplicate songs in your Apple Music library
* Deluxe Special Edition unlocks hidden groups, additional filter types, custom icons, and more themes.

Important Notes:
* Apple Music Subscription Required: An active Apple Music subscription is necessary to use DupeSnoop's features
* Manual Deletion Required: Due to restrictions imposed by Apple on third-party developers, DupeSnoop cannot delete songs directly from your library. Instead, songs queued for removal are added to a special playlist called "Dupe Snoop Playlist" which you can open in Apple Music to manually delete the songs
* Library Access Required: DupeSnoop requires permission to access your Apple Music library to function
* Local Library Only: The app works with songs in your local library and does not modify your iCloud Music Library directly

Take control of your music collection and say goodbye to duplicates with DupeSnoop!
