I'm new to riding the subway every day. It's definitely kind of fascinating, but I also want some big dumb rock songs to listen to on headphones to give it some forward momentum and make the trip faster. I usually listen to rambling/ponderous stuff at home while I'm working, but I think the opposite would be good when you're trying to stay awake and motivated. Somehow today "Love in an Elevator" motivated my subway ride a little more, if that tells you where I'm setting the bar.
