Kelly Clarkson's coming back fast, with Piece by Piece, her seventh record, dropping a week from Tuesday. So is Sia, who recently commented that her new pop album, This Is Acting, is ready to go. (She's also on Kanye West's newest song, "Wolves," which is set to lead his album.)

And so it is that the two titans teamed up for "Invincible," a Sia-penned cut off Kelly's album. Spin it above, and enjoy the thumping, motivational vibe, and good luck not singing the barn-sized chorus by the second time it kicks in. Then prepare yourself for "Let Your Tears Fall," the other song Sia wrote for Piece by Piece.

"Invincible" follows "Heartbeat Song," the "Since U Been Gone" singer's latest single, the one with the mushy music video. This one was produced by Greg Kurstin and Jesse Shatkin, who worked on Clarkson's Stronger and Wrapped in Red as well as Katy Perry's Prism and Sia's 1000 Forms of Fear. 

Piece by Piece hits shelves on March 3.
