We are near the end of the year. Are you still worrying about something? Just like the song says, let it go! This song is from the 21-year-old US Disney star Demi Lovato. It came out on Oct 21. People like her sweet voice and lovely smile. But her life is not always sweet. Lovato once had mental (心理的) problems. But she was not beaten (被打败) and bravely fought back. Now she is much better. It seems that there is nothing that can stop her smiling! With this song, let’s say goodbye to the past and greet the new year!
