The problem with me is that I don't stay focused. I just tried the brain.fm thing that is supposed to get you focused, but I break out of it
really quickly. On the other hand, breakcore helps because it's so obnoxious that I switch from focusing on the task to focusing on the music and back. I can't get distracted by the conversation my coworkers are having, because I'm distracted by the breakcore first. The problem is that I can't listen to breakcore for 8 hours a day without going insane. Maybe brain.fm is better for long productivity sessions, but if I get distracted after a couple of minutes than we don't get there.
