"We Found Love" Featuring Calvin Harris
After Harris opened for Rihanna on her Loud tour, the DJ ended up producing one of Rihanna's biggest show-stopping club hits of her career. With over 10 million copies sold, the electrifying track is also Rihanna's best-selling single and the song that helped push Harris into the mainstream as a superstar DJ. "It changed absolutely everything," Harris told The Sun in 2012. "Career-wise it was the best thing that could ever have happened. For example, in America my tune 'Feel So Close' came out about three months before. But when 'We Found Love' came out, the radio started playing 'Feel So Close' like it was the single after. Then that did really well, it charted well and sold a lot of copies."
