In my opinion, Listens to music can be different types of music, it does not have to be rock or pop, it can be lo-fi music which is very popular nowadays for students, most of my friends listens to lo-fi music before taking an exam and they say it is very efficient and useful, and yes listens to music all day can be bad for our ears, but we can take some time off by talking to parents about music or search for music that have positive lyrics and positive melody, it does not mean we have to listen to it 24/7.
