"This concept is referenced throughout the chorus, where the lines "Such a big girl / such big news / such a big talk / your number is up / if you like it or not" are delivered." → MetroLyrics is not a suitable reference for this, as it just displays the lyrics.

I reworded that piece to simply say that those are the words that she sings during the chorus, but I'm wondering if that statement is even necessary for the article. You can go ahead and remove it completely if you'd like.
"which was deliberately done in avoidance of being branded in a similar fashion as recording artist Britney Spears." → this is unclear to whether it's talking about the song being branded or the artist herself being branded as Spears. Maybe reword a bit?
