With the announcement of a new album entitled Shady XV coming on November 28, “Guts Over Fear” is the first single from the project. Sia’s chorus plays the role that we’ve heard from Rihanna on their collaborations (right down the vocal keys and inflections). You can purchase the single HERE.

Not a bad tune, nothing to exciting or new, still very skilled, nice flow @3.46… Sia defo sounds like a Rihiania clone there… And tune that I would listen to once or twice, then skip over on the album…
I’m in total agreement.
