Realize is a track by American singer-songwriter Colbie Caillat from her debut album Coco, released in 2007 after she first gained a large online following for her acoustic songs. The album helped establish her as a leading voice in laid-back, California-inspired pop, and Realize became one of its most recognisable songs thanks to its warm melody and straightforward lyrics about waiting to admit feelings for someone. Years later, the clip continues to circulate in fan edits and short videos, where its familiar chorus instantly signals romance, nostalgia and gentle optimism.
