A cool community/culture project might be rigging a couple subway cars with a device where one could hook up their player (CD or MP3) - and whatever they is listening too, would play throughout the car. The volume would be controlled, but the music (obviously) not. People don't carry their boomboxes around that much anymore - so this might be a way of looking back and sharing. Like this morning - I wanted the whole subway car to be jumping with how I felt inside as I listened to Ludacris. However, most people wouldn’t want to be jumping around at 6:30am to Ludacris. Bless those that do.
