Beets is a media library management system designed for obsessive-compulsive music geeks. It catalogs your collection, automatically improving its metadata as it goes using the MusicBrainz database. It also downloads cover art for albums it imports. Then it provides a bouquet of tools for manipulating and accessing your music. Beets also includes a music player that speaks the MPD protocol, so you can play music in your beets library using any MPD client.
duke is a curses based frontend integrated into the latest version of mpg123. It was written because of the need of a textbased player for playing from a remote computer with telnet or even a text-terminal. It allows you to navigate through directories, add files or whole directories to the playlist, sort, search, randomize select and delete from it. It also parses ID3-tags, shows songlengths and has limited mouse-support.
mp3album.pl is a tool to automatically create album lists from a batch of mp3 files including ID3v1, ID3v2.2 or ID3v2.3 information. It includes logic to split up all files in one directory into separate albums and generates a report file for each album. The reports are customizable through templates and can contain any information found in the ID3 tags. mp3album.pl lends itself very handy when creating an index of a directory containing several albums of music. As Perl currently lacks 'good' Unicode support, the Unicode strings in ID3v2.3 are not yet supported.
