Zach Kale, Emily Landis and Jim McCormick helped Barrett write the song. The singer recalled to The Boot
that prior to their session she'd be thinking back to when she and Foehner were dating during American Idol
. When her family asked how her boyfriend was doing she'd reply, "Oh, he's good. He's a good one. He's a keeper."
Other girls also said the same thing, and Barrett heard "a good one" said several times. So they set out to write a song that is a tribute to finding a man who is "a good one" all the time.
