PlayFader is a simple, elegant app that will smoothly FADE IN (play) and FADE OUT (pause) your music. But, that's not all...
PlayFader will conveniently sit on your status bar (check screenshots) and will PLAY/PAUSE/GO NEXT/PREVIOUS/SHUFFLE your music, even if iTunes or Spotify is minimized or hidden. 
Works with both iTunes and Spotify.
HOW DOES IT WORK?

Select a playlist or song.
Select the Play/Pause icon and enjoy the elegant, smooth fading.
