"Forgiving Me (You Keep)" by Justin Bieber
Even though the ballad didn't make it on the Changes album, Bieber previewed the song in his Seasons docuseries. "This one over here, Hailey, every time I do something stupid she forgives me," Bieber explained. "This girl forgives me left and right. I'm a damn nightmare." We wonder if Bieber ever plans to release it.
