This problem is a combination problem since it did not
indicate that there is a specified order of songs to be played. The type of
combination problem is without repetition. Thus the working equation would be
n!/r!(n-r)! wherein n is the total number of songs to choose from and r is the
number of songs you can choose at a given time. The answer would be 125970.
