Creating interesting playlists can be a frustrating and time consuming task, unless you are happy to rely on artist and album listings. Genre tags help but they are not always correct and don't always take into account the fact that there may be gaps.

Mufin for iTunes is an addon for iTunes that works the same as the standalone program. It analyses the audio in music tracks so that playlists of similar tracks can be generated from one track.

The analysis can take some time but the Mufin addon automatically senses when new tracks have been added to the collection.

The playlists can be generated to a certain length or number of tracks or size.
