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)
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.
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.
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.
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.
