Some players display, or play files, in the order that the file was originally copied to a USB drive or stick. YAFS (Yet Another FAT Sorter) allows the order to be changed to whatever you prefer. YAFS is a multi-platform, open source, freeware, command line utility with a GUI (Graphical User Interface).

PeppyMeter is a software VU Meter written in Python. It was originally developed as the new ‘VU Meter’ screensaver for Peppy Player. With minor modifications it became a stand-alone application. PeppyMeter gets audio data from media players (e.g. mpd) via fifo and displays current volume level in a Graphical User Interface in the form of a traditional VU Meter.
Quod Libet is a GTK+-based audio player written in Python, using the Mutagen tagging library. It’s designed around the idea that you know how to organize your music better than we do. It lets you make playlists based on regular expressions (don’t worry, regular searches work too). It lets you display and edit any tags you want in the file, for all the file formats it supports.
Unlike some, Quod Libet will scale to libraries with tens of thousands of songs. It also supports most of the features you’d expect from a modern media player: Unicode support, advanced tag editing, ReplayGain, podcasts & Internet radio, album art support and all major audio formats – see the screenshots.
Ex Falso is a program that uses the same tag editing backend as Quod Libet, but isn’t connected to an audio player. If you’re perfectly happy with your favorite player and just want something that can handle tagging, Ex Falso is for you.
