Kids Music

My son loves music since he was a baby. Now that he is 4years old and the kind of music he like is mostly adult musics. He love those music that a big guys sing not the kids songs anymore. I played kids song but not all the time. Today he keep asking if he can play some DVD's . He did that since this morning till this afternoon. I am already get upset since he keep put the volume high too loud. I love musics but if it is too loud my ears hurt and that makes me upset. Anyway, i hope he will be a good musician or a singer....(lol)
