Before the official release date of "Empire State of Mind (Part II) Broken Down", it climbed as high as number four on the UK Singles Chart on downloads alone. The success of the song from a high volume of album downloads, led to the song being announced as the second single from The Element of Freedom in the UK. The single was released on February 22, 2010. It also appears on the soundtrack for Sex and the City 2. Keys and "Empire State of Mind (Part II) Broken Down" are featured on new HP Beats Commercial.
Following the release of "Empire State of Mind" in January 2010, Keys stated that she was planning to release a second version of the song featuring only her vocals, as a single the following month. The original takes of Keys' version, entitled "Empire State of Mind Part 2", included both Keys' vocals and a new rap verse from Jay-Z, but the final product did not include Jay-Z. Discussing the record, Keys claimed that it acts as a dichotomy of strength and vulnerability, commenting that "The music is really strong, and the drums are really aggressive, but my voice is vulnerable and delicate".
I definitely wanted to give my version of it and my vision of how I see New York and how it feels to me. I wanted to do it for my style—more broken down, more on piano, more voice and intimacy—so that's what I did. I imagined, 'If I was able to sing this whole song, how would I do it?' So I just sat down at my piano and I kind of broke it down and started singing about New York as I see it, and it turned out great.
