Winamp plays MPEG Layer 2 (MP2) and Layer 3 (MP3) audio streams, and combines extensive functionality with an intuitive interface (see screen shot). It has a full-featured playlist editor and a 10-band graphic equalizer with user-definable presets that can automatically load specific files. It now 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 here. Version 2.50e features increased usability, improved Mjuice support, numerous bug fixes, and more.

Winamp is the winner of the 1999 Shareware Industry Award for Best Sound Program/Utility.
