The song: “Diamonds,” a ballad she co-wrote with Australian singer Sia and producers Stargate and Benny Blanco. It’s believed to be the first single from Rihanna’s forthcoming seventh album.

It’s trending: Oodles of sites began streaming “Diamonds” on Wednesday. The song already has over 50,000 plays on Rihanna’s Soundcloud page.

But is it good? Nah. It’s a power ballad without much power. “We’re beautiful like diamonds in the sky,” Rihanna sings on the refrain, perhaps trying to get back to the our-love-will-triumph ethos of her career-exploding 2007 single, “Umbrella.” It’s a snooze, but to her credit, she’s not courting controversy with this song. “Diamonds” doesn’t feature a Chris Brown cameo. Yet.
