mpg123.el is a package by HiroseYuuji for playing .mp3 and .ogg files with the mpg123 and ogg123 programs. Get it from the author at

Or on a Debian system see DebianPackage:mpg123-el.

M-x mpg123 lists music files in a directory, which you can start playing, and do other things. Tag information is read directly by mpg123.el, and the E key is setup to invoke Id3Edit to edit it.

Volume is controlled by one of several mixer programs (which can be customized) depending on the system type. On a GNU/Linux system the default is aumix.
