When she was four years old, Murphy and her mother moved to Hendersonville, Tennessee, where she began playing piano and writing songs at the age of nine.

[citation needed] Murphy fought for and eventually won custody of her then eight-year-old younger sister, Mariella.

The five-track EP, including "Heart," dropped on iTunes, Amazon and Google Play Music on May 26, 2015.

Murphy wrote on Feb. 8: "Yesterday I received notice that Yoko Ono had filed a lawsuit against me, asking for a cancellation of the trademark that I own for the name 'Lennon.'

I wanted to address the situation to all my fans because without you I am nothing and it's not fair to everyone who has believed in my music not to be properly informed of this pure bulls***."

Murphy says Justin went to his father and Ono "to make her aware of the use, evidently giving her blessing as Arista proceeded forward with the album release and at the same time filing for the trademark.

Its [sic] takes time for all of the legal work to go through, but finally in 2003 I was granted by the United States Patent & Trademark Office the ownership in the name Lennon for musical use."

It accuses me of falsely representing myself and causing confusion in the market place that has damaged ... the John Lennon name."

Subsequently, without Ono's knowledge, Murphy filed an application in the United States Patent & Trademark Office requesting the exclusive right to utilize the name "Lennon" for musical performances.

In 2008, Ono stated she did not sue Murphy, but sought to stop her from getting the exclusive right to the name Lennon for performance purposes.
