In January 1999, critics noted the track "My Life" from Brown's second studio effort "Chyna Doll" for being an "open appeal" to Brown's friendship with Lil' Kim, in which she cited the relationship being "lost for pride", but also contradicted herself after making attacks on "pointed mistresses". Critics indicated the records were in subtle use to diss Lil' Kim, especially since during this time, Brown had been supporting Lil' Kim' rival Faith Evans in multiple interviews. In February 1999, a significant part of the media took note of Brown "suddenly sound'exactly' like Lil' Kim". In late May 1999, Lil' Cease's "Play Around", featuring Lil' Kim and Diddy, was released to radio airwaves and was set to be featured on Cease's debut "The Wonderful World of Cease A Leo". In the song, after Lil' Kim' guest rap, Diddy recites: "Stop trying to sound like her too bitches"; a subliminal diss aimed at Foxy. The line spurred enough controversy that various media sources went on to remark: "It's finally coming out. Foxy Brown bites worse than a pit bull." Additionally, Lil' Kim's guest appearance on Mobb Deep's "Quiet Storm (Remix)" and her second album's title track, "The Notorious K.I.M.", were released as diss records to Foxy Brown. Angered by Lil' Kim' response, Brown collaborated with longtime associates Capone-N-Noreaga on the track, "Bang, Bang." In the track, Brown mimicked Lil' Kim's interpolation of MC Lyte's 10% Dis, and went on to recite: "You and Diddy y'all kill me with that subliminal shit." Towards the ending of her verse, Brown attacked Lil' Kim's grieving for the loss of Biggie Smalls by remarking: "Let the nigga [Biggie rest in peace, and hop off his dick, bitch do you."
