Throw away a file in the Finder, and you know to find it in the Trash folder. Delete an image or video from Photos, and it’s moved to the Recently Deleted album. But where do iTunes and Music in macOS put a deleted file? Also in the Trash.
If you have iCloud Music Library enabled via an Apple Music or iTunes Match subscription, iTunes or Music will also warn you when you attempt to delete songs, albums, or other media managed as music that the items will be deleted everywhere. When you delete music with iCloud Music Library enabled, the file is removed from the synced set of items stored your iCloud account and also any downloaded version is deleted from all your iCloud-linked devices.
