I'm thinking of playing music loudly during the daytime as a music student
Why do you need your music to be so loud?
It's logical. I shouldn't bother anyone during the day because everyone is awake
You should keep your music down during the day. People are trying to study.
Why are you so concerned about other people's wellbeing?
I think that it is common curteousy to play music at a lower level. You do not want to disturb people while they are trying to study for their own classes.
