  4. The DJ can also remove files from the emission playlist.
  5. The DJ can also change the order of the audio files in the emission playlist.
  6. The start time, end time, length, fade in and fade out times of each audio file can be set.
  7. Once the total length of the the emission playlist has reached the exact length of the time slot reserved for the show, the user is notified.
  8. When the DJ has finished composing the playlist, she returns to the emission interface.

Post-conditions for main success scenario

  • A playlist is associated with a show
