One possible version:
Dear Headmaster,
We have had a discussion about whether to play music during the break. All the students in our class gave their ideas.
Most students agree that the music should be played. They think listening to music can make them feel happy. Besides, music helps them relax after hard work. What's more, music can help them improve the study efficiency.
However, some students disagree. They doubt whether they can get expected results by listening to music, as the break is short. In addition, some students are still lost in music in class, which has a bad effect on students.
I think what we need is peace instead of the noise produced by music. So I disagree.
Yours sincerely,
Li Bing
