Beethoven and Bach ride the MTR

It takes me about 30 minutes to get to work. I leave my building and hop on a mini-bus, ride it to the MTR (mass transit railway) station, board a train to Kowloon Tong, and walk about 10 minutes to school. There are some mornings when everything seems to run smoothly and then there are those mornings when the timing of buses and trains seem to be off and people conspire against me to walk right in my path. As I impatiently stumbled through the Kowloon Tong MTR station this morning, I recognized a familiar piece of music playing over the public speakers. It was Beethoven's Fur Elise. I've heard this tune before in the MTR along with some of Bach's Cello Suites. I finally asked myself why these classical pieces are being played in the MTR. BAM! I wonder if there is a conscious effort to play this music because it can have a calming effect, therefore calming the people's emotions as they struggle to navigate their way through the busy station. Instead of a dose of high art, could it all be a mind game to help control the masses? What do you think?
