Download of MickTagger 2.4 for Mac was available from the developer's website when we last checked. We cannot confirm if there is a free download of this app available. We recommend checking the downloaded files with any free antivirus. The program lies within System Tools, more precisely File Managers.
From the developer:
Mick Tagger is a music playlist organizer. You can use Mailbox Monday to group any number of playlists together by feeling, genre, artist, year, and whatever criteria you may think of. This grouping will create a new playlist. With auto-like, Mick Tagger will automatically save a track to your Liked songs after playing it all the way through a couple of times.
Another smart feature is the Evergreen Playlists.
