"Little Things" by One Direction
From the band's second album, Take Me Home, "Little Things" wasn't originally supposed to be a One Direction song. The band told MTV News that they sort of recorded it by accident. "We went in to record a different one of his and he said, 'I've written something else if you want to hear it' . . . he wrote it and then played it to us in the session when we were supposed to record something else and we said, 'All right, we want to record that now.'"
