Have you noticed if there is a difference in your preferred listening habits in the day and then in the night?
For instance, are you more prone to listen to easygoing music in the nighttime and louder, faster music in the daytime?
I prefer to listen to louder music during the day and calm music at night. I agree that it may depend on the mood at a particular point in time. There are instances where I never want to listen to any kind of music.
