I listen to music at work all the time to avoid distractions. When I do my 10 minute routine, I listen to music that gives me a dopamine rush during the intense part of it to help boost my performance. I can replicate the rush most of the time, but I do believe that finding new songs after a few weeks is good.
When I listen to my workout playlist at any other time of the day, it actually helps boost my productivity and motivation level because my brain has learned to associate such songs with pushing myself. So I actually do this when I'm feeling a bit tired to get another boost.
Also, invest in great headphones. The new EarPods really enhance my workout experience, so much so, that I now look forward to my early morning workout when I wake up to get over my grogginess.
