well the ""thinking"" behind it is "everything can be music"
and by making this "composition" he tried to invite the people to take a time to enjoy 4 33 mins of silence, have their own interpretation of what they would hear , even create the melodies in their head

jesus... music fame was just a "who is going to be the most stupidly overated" competition
and the worst is they made a living out of this
