Windows only: If you're facing the monumental task of editing your iTunes metadata and files, and there's no easy way to pull it all off, check out Teridon's iTunes Scripts before giving up your free time. Teridon's iTunes Scripts is a collection of small scripts available as both PERL and EXE applications covering a wide range of iTunes-related tasks. With the small scripts, you can do all manner of things: create playlists of all your one-off single tracks, bulk add M3U playlists, embed iTunes album art right into the ID3 data of the songs, remove duplicates, and import your song ratings from MediaMonkey. Before spending hours tinkering with your iTunes library, it's worth checking to see if one of Teridon's dozens of iTunes Scripts will turn your Saturday of data-entry Hell into a five minute automated task. Teridon's iTune Scripts are free, open-source, and Windows only.
