Leisha Hailey of "Murmurs" was former girlfriend of kd. Under such a situation, kd produced some songs such as "Big talker", "I'm a mess", "Genius", "Underdog", "Don't lie" and "Sucker upper". Some fans hated Leisha because she was much younger than kd. But if you listen the song "Genius" which Leisha wrote, you will be mooved. Because it means kd is genius!
