Great travel day performance at Copenhagen Airport

Every morning I have to squeeze to get into the MRT.
I could see the facial expression from the  people in the train that they feel stressful with so many people in the train.
Then I have an idea, why don't MRT play some relaxing music in the background to so that everyone has a more pleasant trip to work. Shortly after the thought, I came across this mob dance at Copenhagen airport in youtube. It was nice and in this video it was playing my favorite song from the movie Grease. What a great way to start my day.
