Dubbed "Alive," the song was written with a little help from indie heartthrob Tobias Jesso Jr. and motherfucking Adele (!!!). And while that may cause some concern for a few Sia diehards, we can assure you that it's still solidly self-affirming, soul-shattering Sia -- disco-tinged electro-pop and all. Get ready to belt that chorus in the club.
