I used to really enjoy floppotron-style stepper motor music while in the coding zone. As a musician I sometimes get distracted by voices of different instruments, so the stepper motors give a nice homogeneous tone. Unfortunately, I can rarely listen to anything with both ears anymore (always listening for either phone calls at work all day or child cries at home at night). I just play whatever through one headphone but the opportunities for interruption make it a lot more difficult to get in the zone.
