Listen to Rihanna's new single "Diamonds"

Following up on last year's hit record, "Talk that Talk," Pop princess Rihanna has finally debuted "Diamonds," the first single off her forthcoming seventh album due out in November.

Written by Australian singer-songwriter Sia and co-produced by pop music's prolific Norwegian duo, Stargate, "Diamonds" moves along at an unusually easy-going tempo for a musician whose songs always seem to end up on the club floor.

Rihanna has described the track as "hippy and happy," and the song's cover art features the singer's hands rolling a joint filled with diamonds.

Writes MTV's James Montgomery:

[Rihanna] displays a marked level of (dare I say it?) maturity, one evident in the restrained production and perhaps best exemplified by the first mantra she lays on us: 'I choose to be happy.'

Idolator calls it "subtly, rather than explicitly, tribal" while SPIN notes it's "relaxed and uplifting tone."
