Norwegian singer-songwriter Ina Wroldsen is probably best known as a writer for other high-profile artists like Shakira, The Pussycat Dolls, Leona Lewis, Britney Spears and more recently Tinie Tempah and Rag 'n' Bone Man. In 2015 Calvin Harris released How Deep Is Your Love featuring Wroldsen's vocal, which became one of the year's most streamed songs. Her career as a solo artist got a major boost this year with the release of debut EP Hex and smash hits like Strongest and Favela.
