Winamp plays MP2 and MP3 audio streams and combines extensive functionality with an intuitive, customizable interface. It has a full-featured playlist editor and a 10-band graphic equalizer with user-definable presets that can automatically load specific files. It also features Windows Media Technology 4.0 input/output support and the industry-standard Fraunhofer MP3 decoder. This download no longer includes VIS/DSP plug-ins; you can download them separately on the Winamp site.

Version 2.91 includes various bug fixes and miscellaneous performance enhancements.
