I like the way this cover in a humorous manner aggressively owns the narrative. The miming of puppetry after the lyric of "I want you to notice when I'm not around" is a delight.
Sara Bareilles covering Sia's Chandelier. She's got an amazing voice, I'd never heard anything other than her couple radio hits and had no idea she could sing like this. (if the timestamp doesn't work, skip to 1:35 or so)
