My Favorite Song (of ALL time)

My favorite song is "Let it Go" because I memorized it by heart and I sung it for my school talent show.  I like it because it repeats itself a couple of times like "Let it Go" "Let it Go" "Let it Go!!!"  I also have another favorite version of the song.  It's by Demi Lovato.  I love both of them because they are a bit challenging and a bit not.
