People who have collected MP3s and digital music for years often end up with duplicate songs, missing album covers and completely inconsistent file names. A music-library cleanup service can organize those files into a neat collection. The customer provides the music they legally own and explains how they want it sorted. The work can include correcting filenames, arranging artist and album folders, adding supplied or properly sourced metadata and identifying duplicates. A basic package can cover a few albums, while larger packages can handle thousands of tracks. Original files should be backed up before anything is renamed or deleted. Playlists can also be created around genres, moods or decades when the customer requests them. This service does not involve supplying copyrighted music. The value comes from taking a chaotic collection and making it easy to browse, search and transfer between devices.
