"We Both Know" brings together two of the biggest and brightest voices of the 21st century—Colbie Caillat and Gavin DeGraw.

The first release from the soundtrack for Relativity Media's Safe Haven is a powerful, poignant, and poetic duet that floats to heavenly heights on resounding piano chords and soaring strings. DeGraw and Caillat's voices meet in between with equally soulful delivery, matching for harmonies that instantly impact. It's an irresistible ballad and a historical moment for modern pop. Rarely, do we get to see collaborations on this level anymore, and it's an invigorating breath of fresh air.

Film history has been punctuated by magnificent soundtracks that match their inspiration's sense of wonder. Based off this inimitable gem, it's automatically clear that the music for Safe Haven stands on par with the likes of both Titanic's epic pop prowess and Garden State's subtle ruminations on life and love.

"We Both Know" transcends both sentiments as one of the best pop songs of 2012. It's the kind of tune you'll hear at weddings someday, and you'll know it the second it begins.
