If you have obtained files with the extensions .MPC or possibly .MP+ then you have obtained Musepack audio files. Musepack is a lossy audio compression like MP3 for example, but it produces better quality than MP3. Musepack is based on the MPEG-1 Audio Layer 2 standard (MP2), but includes many improvements. It is believed by audiophiles to be one of the highest quality lossy compressions available for music.

Foobar 2000 is an excellent software audio player that supports Musepack. If you wish to burn Musepack audio files as an audio CD, you can download a plugin for MPC files for Nero Burning Rom here .
