I'm a music student, so I'm thinking about playing music loudly during the daytime
Won't that be annoying to your neighbors?
Yes, I know it's wrong, and I don't want my neighbors to get angry with me.
It's okay to play music as necessary for your studies, but you do need to be considerate of others, so you should only play it as loud as it needs to be for you to hear. Your neighbors will have every right to be angry, and to ask you to turn it down if it is loud enough for them to hear.
It's not like it's 24 hours a day. I have to study sometimes, you know. I don't have time, even to be considerate.
Being inconsiderate of your neighbors is not an option, and being busy is not an excuse. How would you feel if you're neighbor's kids practiced their bagpiping -- off pitch and out of key because they're beginners -- at all hours of the day and night?
