5. Lorde, 'Melodrama'
An electro confessional, as Lorde whispers her secrets and the city sings them back to her. As someone who didn't get anything at all about Lorde's debut, the title of which I respectfully decline to type, I didn't see Melodrama coming until "Green Light" clobbered me, with that disco-gospel piano broadcasting the boom-boom-boom in her heart. Lorde isn't coy about flaunting how new she is to the adulthood thing. (Ordering different drinks at the same bar is ... not so unusual, honestly.) But the "I want it, I want it" rush that pervades the album is the excitement of a girl who just noticed the entire world under her feet is a light-up dance floor.
