Play MPC, MPP and MPPlus audio in Winamp with MPC Plugin
Winamp does not support natively mpc playback. In order to play mpc (and MPP or MP+) files in Winamp you need an MPC Plugin.
The Winamp MPC Plugin supports ReplayGain, Crossfade Plugins and ignores ID3v2 tags (not supported by MPC in any case).
To install the plugin, download and extract the zip file, then copy in_mpc.dll to the Winamp “Plugins” folders, usually at “\Program Files\Winamp\Plugins”.
Restart Winamp (if it is still open) and you are ready to rock!
