UModPlayer is a multiplatform console module playing software for UNIX systems (such as Linux or NetBSD). It provides full sound option customizing, playlist support (with the ability to move, edit, import, and save lists), a WAV and AIFF writer, a file browser, a message viewer, an instruments viewer, and much more. It uses LibModPlug and LibAo.
ModPlugLine is a module player that uses ModPlug for mod rendering. It runs in the console (through curses) and uses the OSS for output. It supports all modules supported by ModPlug (S3M, IT, XM, MOD, UMX, etc.) except for compressed modules (S3Z, RAR, ZIP, etc.). ModPlugLine features great sound because it uses micro volume ramping (noise reduction) and polyphase oversampling. It also has an XBass feature to boost low-frequency bands.
Libmmoss enables the Linux version of Netscape Navigator/Communicator to play sounds from Java applets. It is a replacement for Netscape's implementation of (the Java class) sun.audio.AudioDevice (including some JRI native C code). It should work with either the OSS or ALSA sound drivers. The latest version will also work with EsounD.
GtkSC is a GTK/Perl based application for viewing the list of streams available via SHOUTcast without waiting a long time for Netscape to draw the HTML tables. It will launch your favorite MP3 player and play the selected stream (provided you have an MP3 player capable of playing HTTP streams)
