Music Player Daemon (MPD) is a flexible, powerful, server-side application for playing music. Through plugins and libraries it can play a variety of sound files while being controlled by its network protocol.
GramoFile is a computer program, running under the Linux operating system (and some other UNIX-like OSses — and even DOS/Windows now!), with the main goal of putting the sound of for example gramophone records on CDs. It is able to record hours of CD quality music, split long sound files in separate tracks, and remove ticks and pops from recordings.

MP3val is a small, high-speed, free software tool for checking MPEG audio files’ integrity. It can be useful for finding corrupted files (e.g. incompletely downloaded, truncated, containing garbage). MP3val is also able to fix most of the problems. Being a multi-platform application, MP3val can be run both under Windows and under Linux (or BSD).
The most common MPEG audio file type is MPEG 1 Layer III (mp3), but MP3val supports also other MPEG versions and layers. The tool is also aware of the most common types of tags (ID3v1, ID3v2, APEv2).
Squash is a C / Ncurses based Unix music player. It supports mp3, ogg and flac through libraries. Squash uses statistics to determine songs to play automatically. It garners this information through whether or not a song is skipped. Squash also avoids picking the same song twice. Thus Squash is like a radio station that plays the songs you like — and you don’t even have to call in requests!
