Winamp with AdPlug plugin
Nullsoft Winamp is a fast, flexible, high-fidelity music and video player for Windows. Winamp supports MP3, CD, WAV and other audio formats, custom appearances called skins, plus audio visualization and audio effect plug-ins. additional features including free-form skins, a new decoder, built-in cross fade, and an advanced Media Library.
AdPlug is a free, cross-platform, hardware independent AdLib sound player library, mainly written in C++ and released under the LGPL. AdPlug plays sound data, originally created for the AdLib (OPL2) and Sound Blaster (Dual OPL2/OPL3) audio boards, directly from its original format on top of an emulator or by using the real hardware. No OPL chip is required for playback.
AdPlug itself is just the backend to many different audio player frontends, which are also being developed here. There are plugins for popular audio players, like Winamp and XMMS, as well as stand-alone players for many different systems available.
