From personal experiences, I found that having music turned on in the locker room helped my team to loosen up and get hyped. I like to listen to music on my own in between classes or working on a paper/project. Music can help to motivate me, but also helps me drown out what is around me and focus. I also use it during exercise, with something upbeat that I can match the beats to with my steps or just stay motivated.
I think music can be used in many ways, and is very universal in its uses.
