Tibor Andre has announced Tune-Instructor 3.5 for Mac OS X, an update that provides 25 workflow options for organizing iTunes files, plus playback controls.

An interactive widget permits rating, playback, progress and title information within the notification center. The app allows for custom editing of the ID3-Tag, which contains all metadata of an MP3 file. Users can organize their song libraries, lyrics, artwork, files, and folders however they wish.

Tune-Instructor 3.5 (http://www.tune-instructor.de/en/start.html) requires Mac OS X 10.10 or later and iTunes 8.2 or later. It's donationware .
