M3Unify v1.2.3
M3Unify is a flexible M3U playlist creator and file exporter that will allow you to load a USB thumb drive or SD card with copies of your iTunes songs the way you and your audio player want. M3Unify can archive playlists and audio files to a folder, volume or portable media and includes options to create Artist/Album sub-folders, rename files, convert to AAC or MP3, and more.
This latest version fixes an issue with embedded artwork in converted AAC files not appearing in some Android players (and perhaps other non-Apple devices).
For OS X 10.8 and later. M3Unify is $5.00, but free to use in demo mode with a fifteen track limit. This is a free update for registered users.
