Rihanna is in “big ballad” mode “Diamonds,” the lead single off her currently untitled seventh album. There’s not much to criticize here. The lyrics are simple and don’t clutter Stargate and Benny Blanco’s triumphant arrangements. And credit to Rihanna (or studio tricks), her voice remains strong and not drowned out by the grand production. Expect this to be another hit for the Bajan bad girl.
