For Those Who Manage Those Who Can't Escape

In the movie The Shawshank Redemption, I found the scene where the main character plays music for the other prisoners to be quite moving yet I realize that they are in prison for a reason and you also might not have an easy to locate yet soothing melody to calm everyone's nerves.  Regardless, for the absolutely best behaved prisoners, an area with soothing music to calm the nerves and help them get through there time in prison, there could possibly be some kind of area where some melodies are played.  I believe that Norway might find this information particularly helpful and other countries which are seeking to apply a merciful update to their prison system.  Nevertheless, Norway might have already explored the idea.
