"Chasing the Sun," Duff's new song, features delicately plucked acoustic guitar and keyboards as the singer laments the daily rat race: "Why am I in such a hurry?" she asks. "Always getting up too early / So fast, everything is blurry."

By the time the chorus hits, she's decided that she's going to lay low and relax for a bit, opting to "get it while our hearts are young" and live in the moment.

"Chasing the Sun" marks Duff's first song since her signing to RCA Records. She's since been working on a new album, her fifth and first since 2007's Dignity.
