At the , the beat amplifies and Perry's lyrics become more aggressive as she commands "Now Look at Me!", signalling to her ex that she is still strong, regardless of what he tries to do to bring her down. The beat reaches a peak at the chorus, and Perry's tone and the song's lyrics become more aggressive and prominent as she sings, "This is the Part of me that you're never gonna ever take away from me." As the song continues, Perry's lyrics become strong and empowered: "So you can keep the diamond ring/ It don't mean nothing anyway/ In fact you can keep everything Yeah/ Yeah Except for me".

James Dinh of noted that "the pop star appears strong, bold and just a tad resentful after a breakup" on the track. His analysis of the lyrics observed that "The singer declares herself unbreakable after a breakup, evident in lines such as "Days like this I want to drive away/ Pack my bags and watch your shadow fade/ 'Cause you chewed me up and spit me out/ Like I was poison in your mouth/ You took my light, you drained me down/ But that was then and this is now, now look at me."

I wrote it two years ago, which is funny because everybody is like "God, it sounds so current," and some people that I work with were like "You should just say you wrote it a couple of weeks ago." I'm like "I'm not a dick, I'm going to tell the truth." I wrote it two years ago when I was writing and recording Teenage Dream, [but] it didn't feel right on the record. I would've had to take out one of my other songs that [made the album] a nice, complete package.

A reviewer from criticized Perry's decision to create an uplifting song about such a serious subject matter as divorce: "Framing the song in terms of her divorce from Brand, though 'Part of Me', puts a much more somber and serious spin on things. This is no mere breakup. It's the demolition of a marital covenant. So no matter how bad things were in her relationship, no matter how much better she feels now, no matter how cathartic the pulsing beats (courtesy of hitmeisters Max Martin and Dr. Luke) might feel, the ultimate end here is a very sad one indeed." Priya Elan of panned the song: 'This is the part of me, that you're never going to take away from me,' "she sings in that strange angry robot voice of hers. The sentiment, as ever, is punch you in face crystal clear and probably meant something to one of the (probably) 17 writers who wrote the song. As it stands, it's another de-humanised slab of radio pop from Perry INC."

We used only , no actors or actresses. We used all of the Marine's equipment and they were so lovely to us, I always have fun even though it's a lot of work. Even though I was sore and exhausted, I was so educated on people in the service, who I've always respected but the stuff they go through, and the kind of loyalty they possess, it's very communal, and community.
