The "binaural" features a binaural music track with theta waves in background to take you deeper, but the first one listed has no music for those who can't listen to binaural beats due to health reasons. This file increases the desire for the listener to be a pig - not as in the animal, but as in sex pig, pain pig, toilet pig, cigar pig, humilation pig, bondage pig, or any other number of 'pigs' Check out more pig files at http://hypnosuperior.com
