Ask Embla is the pairing of two incredible songwriters: Arnthor Birgisson and Ina Wroldsen, both of whom are responsible for penning tracks for some of our favorite pop stars over the past decade.

Wroldsen, known as the unofficial sixth member of The Saturdays, has penned a majority of the group’s output, including “If This Is Love,” “Up” and “Work” from Chasing Lights, “Forever Is Over” “Ego” and “One Shot” from Wordshaker, “Higher” and “Karma” from Headlines and “Notorious,” “Faster” and “White Lies” for On Your Radar. (Basically, all the amazing ones.) She’s also crafted smashes for several other artists—from Samantha Mumba to The Wanted to, of course, Britney‘s almighty Femme Fatale bonus track (and Kylie‘s favorite!), “He About To Lose Me.”

Arnthor Birgisson’s legacy as a songwriter dates back even further, responsible for a plethora of pop cuts — everything from Jessica Simpson‘s “Irresistible” to Janet Jackson‘s “All Nite (Don’t Stop)” to Shontelle‘s “Impossible” to Britney’s Circus ballad, “Out From Under.” (Oh, and Stephanie McIntosh‘s ever-amazing, Summer Heights High-approved “Mistake” too!)
