A Sarasota, Florida act called Boyce Avenue has covered Rihanna's "We Found Love." The rendition features piano and sparse percussion and is pretty nice.
Boyce Avenue covers lots of popular songs on their YouTube channel, where you can also find renditions of Katy Perry's "Teenage Dream" and Adele's "Rolling in the Deep."
Of course, YouTube is chock full of covers of "We Found Love" from unknowns, kinda-knowns and well-knowns, like Coldplay. Here's Boyce Avenue's version, Coldplay's version, a version by a group of male singers called Ahmir, and Rihanna herself. Whose do you like best?
