I often lack the motivation to track my working time. Some argue it is not useful. But I think it is useful to see how I spent time (i.e compare the time spent, with the task done)
Since I often listen to music while working, I built a small Chrome plugin to track time with background music. Whenever the timer starts, it also plays a list of selected songs from youtube. It motivated me to track time.
I'm considering to publish the plugin. Let me know what you think.
