Let it go, Just like your breath! For it'll get disastrous; If you hold on to it, Too long! Let it go just as I let her go! "Let It Go" is a song from Disney's 2013 animated feature film Frozen, whose music and lyrics were composed by husband-and-wife songwriting team Kristen and Robert Lopez. The Sam Tsui❤ mashup version is the perfect catch. To read my other composition on my top 99 playlist use the tag #songstolove!
