DON’T let the heavy smog (雾霾) get you down. Listen to this song. It shows you a beautiful dreamy world. It is from the US band Owl City. If you think they’re a big band, think again. The band has only one person! Adam Young, 27, is the solo (唯一的) band member. He is the singer, songwriter and the producer (制作人). Although he stands alone, his music has cheered many people up. Why don’t you become one of them?
