Необходимо написать о возлюбленном предмете (в данном случае музыке)И начать надобно

My favorite subject is music. I Like music because I love to sing different songs with the class, it gives a lot of energy and energizes as well as the mood is bright and cheerful. After class, I sing the song that we sing all day long. But unfortunately, only a music lesson once a week, it makes me sad.'s My favorite subject!
