Mac MP3 Utilities

Trax 2.7.3
From the developer: Trax is a freeware utility which creates playlists compatible with just about every MacOS mpeg audio decoder (Vamp, MacAMP, AudioActive, etc.) The only requirement is that they support the Open Documents apple event. Trax is designed to mimic the finder interface for arranging files: i.e. it displays files in a hierarchical view, categorized by their parent folders.
