Local Track Matcher
Match unplayable local tracks in your playlists (for e.g. from previous iTunes imports) with tracks that are available on Spotify.
When Spotify came out, there was an option to import your tracks from iTunes and other local media. This was to make the transition from your old file-based music library to a new all-online library easier. Back then Spotify also tried to match your local music with songs that are available on Spotify. Later in time the iTunes import functionality was removed and with it the possibility to match local files. This script is an approach to manually match previous local files, making them available on all your devices without the need to provide the according .mp3/.whatever file.
