"Don’t listen to music while I run? I respect your right not to, but I can’t hear your argument why. Music’s too loud. Sorry."

Can Music Make You a Better Runner? by Matt Fitzgerald sums it up nicely.
In a nutshell:
Because the brain essentially chooses to impose fatigue based on a prediction of where the body's true physiological limits lie, the brain has some flexibility in setting performance limits. When an athlete is highly motivated, the brain will risk a bit more and allow the body to come a little closer to the point of self-harm in pursuit of better performance. All kinds of factors may influence an athlete's level of motivation, and music appears to be one of them.
I don’t know about self harm. But, I do know that running is hard. For many of us, music makes it more bearable. And for some of us, music is a pleasant and much needed distraction. For me, the music I listen to on the road enhances my overall experience like nothing else can. Does it make me faster? The jury is still out on that. Does it matter? Nope. Running and music make me happy. These days, that’s about all I need.
