abcde is a frontend to cdparanoia, wget, cd-discid, id3, and your favorite Ogg Vorbis (the default), MP3, FLAC, Ogg Speex, or MPP (Musepack) encoder. It grabs an entire CD and converts each track to the desired format, then comments or ID3-tags each file, all with one command. It supports multiple output in a single CD read, the creation of a single track from a CD, resume operation, CD concatenation, volume normalization, gapless encoding (with LAME), parallelization, SMP, proxies, customizable filename organization and munging, playlist generation, distributed encoding via distmp3, and more.

cdenc lets you encode whole audio CDs in a special directory which can be burned on CDROM afterwards. It tries to extract all necessary informations for the mp3info tags from the CDDB. It also produces HTML files using wish, including the coverpicture of the disc, tracks.idx files for the sajber jukebox, long filenames for a conventional player, and bitmaps with the cd titles for usage with the Yamakawa/Raite MP3 player AV715. cdenc makes it easy to produce MP3 CDs which work fine with Sajber Jukebox, WinAmp, and Yamakawa the same time.
Chango is a system for cacheing MP3 files from multidisc cdrom drives. Since you can't actually mount different discs in the same physical device simultaneously, this software will cache the files you need off to a predetermined cache, so that all of the needed files will be available simultaneously.
ctrlxmms is a small Perl script designed to increase the useability of XMMS. With it, you can use most of the common GUI functions of XMMS from the CLI. You also have a few handy commands which are not available from the GUI. Together with lirc and a remote (eg. Anir Multimedia Magic), this is a wonderful tool.
