Appearing on this channel are mixes of popular songs that have been stripped to the stems, remixed and presented in different audio makeup from the standard studio mixes. Vocals, specific instruments or effects are enhanced, omitted, digitally altered for effect or are repositioned in left or right channels to create a different, often wider stereo sound separation from the what is customarily heard on the radio. Some mixes have been re-recorded in two-channel stereo from a quadraphonic or 5.1 audio signal.
