Florence & the Machine's "Shake It Out" Sheet Music on Chromatik

Florence Welch churns out these uplifting arena rock anthems so quickly that she’s beginning to sound like a motivational speaker. Not that Welch's operatic vocals and exhilarating lyrics sound cheesy; rather, Welch has developed such a strict regimen of unbridled optimism that their production feels like clockwork. In an interview with MTV News, Welch mentioned that she wrote "Shake It Off" while combating a hangover. That fact alone perfectly summarizes Welch's work ethic, to write this positive song (much less think about those high notes) during such a fatigued moment can only come from a songwriter that knows how to effectively dole out work and play.
