streamiumd aims to be a simple-to-use, yet feature-rich daemon that runs on a server containing MP3s and M3U (playlist) files. It requires very little to get it running (Perl and MP3::Info), runs fast even on old machines, and allows your MP3 collection to be browsed from your Philips Streamium (tm) MC-i250 or MC-i200. It can serve to multiple devices simultaneously, has its own built-in HTTP daemon, can read HTTP URLs for Internet radio from M3U files, and can run on whatever port you choose.

Mr. Voice is a specific-purpose Perl/Tk front-end for an MP3 database. It was written to provide an easy-to-use MP3 solution for the production booth of an improv comedy troupe, and as such is tailored to providing quick searches and playback of MP3s that are split up into categories. While not intended to be a standalone desktop MP3 player, others in a similar situation may find it useful.

It can also generate a list of music files to be loaded onto a portable music player device.
SlimServer provides an elegant and easy to use interface for playback of music stored in many audio formats, and supports Internet radio stations, playlist management, Web access, and an infrared remote control.
