Lee, it's derivative of one type of establishment where the box
was first in use.  See 'Politically Incorrect' definition below from
Webster's New Collegiate Dictionary 1960:

  juke, or jook joint  [Appar. of West African Origin]
  Orig. southern U.S. Orig., an out-of-the-way shack used by Negro
  turpentine workers as a drinking and dancing resort; hence any
  roadhouse or dancehall or like resort for drinking and dancing
  esp. to the music of an automatic player of phonograph records that
  plays one record on deposit of a coin in the slot, called a jukebox
  or juke.
