From the developer:
MusicMaster is an application that allows you to perform a number of useful operations on your digital music collection like changing the case of the titles, removing/fixing broken tracks, or performing search-and-replace across all tags.
MusicMaster can operate on your whole iTunes library, on selected playlists, or on folders of music, which works even without iTunes.
