The Swedish songwriter, who has penned tracks for both Justin and Britney, as well as the Backstreet Boys, Adele, Katy Perry, Pink, Justin Bieber, Taylor Swift, and The Weeknd, will be presented with the honour by King Carl XVI Gustaf of Sweden.

Italian opera singer Cecilia Bartoli is the other winner of the 2016 prize, which was founded by ABBA's former manager Stig Anderson in 1989 and is shared annually by a pop artist and a classical musician.

Justin Timberlake says of Martin's win, "No one deserves it more. You are a master," and Britney adds, "I think you're a genius, it's such an honour to work with you. You've been a part of my career from the beginning."

British pop star Ellie Goulding, who worked with Max on Love Me like You Do, congratulates him on a "very well deserved Polar Music Award", Katy Perry praises the songwriter's "back and forth" in the studio, adding, "He sets the scene to be really creative," and Pink declares, "You blow my mind and I'm really proud of you."

Max, whose most famous songs include Britney's ...Baby One More Time, Katy's I Kissed a Girl and Roar, and Taylor Swift's Shake it Off, will pick up the prize from the King at a ceremony in Stockholm on 16 June (16).

He adds of the win, "Thank you very much. This is a great honour. See you in Stockholm in June!"

Previous winners include Sir Paul MCCartney, Sir Elton John, and Stevie Wonder.
