Dialing back arousal for more difficult tasks actually produces better results. More control, better performance is how I'd think about it. Match the right kind of 'music' to your needs.

Athletes commonly listen to their playlist seeking the right "arousal level." Share something great. Some need calming (0:56) and others more stimulus (2:36) or a lot (3:44).

Of course, others find a different path.
