No matter how hard you try to keep your iTunes library tidy, sooner or later youll find cobwebs growing in its corners. () helps you take a broom and dustpan to the far reaches of your digital music collection.

For a set of iTunes-tweaking Perl scripts, TrackSift offers a handsome front end. Creator Doug Adams has given it a clean, pleasantly animated interface that occasionally gets crowded, but always presents its options clearly. The program takes a minute or so to scan your library the first time it opens, plus a few seconds on each subsequent launch, but the delay never proved tedious.

The apps skills occupy three categories. Under the Clean tab, you can delete any track listings that point to now-nonexistent files, sweep away empty playlists, or remove needless genres from your librarys listings by shifting them en masse into another genre.

Under Find Tracks Without, you can create playlists of all the songs that have no lyrics and no album art, or a list of songs you havent added to any other playlist. (Note that TrackSift wont automatically fetch art or add lyrics to any of the tracks it gathers.) Its Preferences let you specify which genres to include or exclude in your search, and set length limits for the songs it compiles.

In the Make Special Playlists category, One Hit Wonders scooped up all the artists in my library with just one track to their names, while Two-Fers and Three-Fers create fun compilations with two or three consecutive tracks from each artist.
