Why does music sound so good after some workout and nice cool weather? I have the window open with a nice cool temperature(outside with the cool breeze in the night), and I generally find that there is an ideal situation music sounds the best. To me, this makes a difference for some reason. Also, being in good physical shape makes a difference in how optimally the auditory system work I believe. So, after exercise, music sounds pretty good, but also being in good generally physical condition will have an effect in how you hear.
