I have a theory I'd like to run by the readers of this list.  In a 
    nutshell it goes like this, 
     
    
      "...people can handle more challenging music if it's 
      accompanied by a cool video."
       
    Do you agree?  Have any of you added video to your looping music 
    and discovered it helped increase sales?
     
    Kind regards,
