MP3Bar wraps mpg123 and puts a 'lil NSStatusItem in your menu bar. Click show playlist, and click the add button, or drag 'n drop them right onto the table to import files. Simple! I'll be working on it bit in the coming weeks so if you spot a bug/oversight/error tell me :) I've also provided the source, so feel free to fiddle with it and make your own changes.
