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.

It displays a list of all the nap servers and current statistics for each server (users, number of MP3 files, gigabytes), and provides the ability to ping individual servers and check the network lag time, a facility to save the list of servers and statistics to a file, and the ability to refresh statistics for individual servers or all the servers.

With rebot3.pl you can also add or remove ID3 (version 1) tags to/from the MP3 files.
