If your a boy, prob not cuz bitul Torah. If your a girl, my opinion would be that if its not for an extended period of time and you’re not throwing off responsibility… Why not!
Technically any time wasted is bittul Torah if you are a man. However most people today are challenged in the area of using time wisely. I will tell you that when you are learning or davening be careful to maximize that time. However a person is allowed and must have time to recharge and relax. You aren’t a machine. If you truly feel that you waste hours a day then you have a problem but if you truly need to listen to music for an hour a day to feel healthy and sane it’s probably a mitzvah to do so. Hashem doesn’t want depressed Jews.
