iTunes Toolkit

iTunes Toolkit brings you the features that Apple left out of iTunes.
iTunes Toolkit simplifies the process of adding new songs to your library.

It will scan your hard drive for new tracks and import them into your library. Alternatively, the program can find all music tracks that are not in your iTunes library—regardless of date. Not only will it add tracks, but it can also automatically organize them in one playlist or several playlists by album or folder location.
