When your lemons don’t sell at the farmer’s market, you make some damn lemonade anyways. Such was the mentality of recent Roc Nation inductee, Grimes, when Rihanna declined a song she’d written for the pop star.

With help from her longtime producer-colleague, Blood Diamonds, Grimes also went ahead and laid down the track for good, which Zane Lowe debuted on his BBC Radio 1 show this morning. Featuring magnanimous trap stylings and plenty of room for someone, say Kendrick Lamar, to freestyle over - lets see if this makes Rihanna have second thoughts.
