[2] "Grass Ain't Greener" is a mid-tempo alternative R&B and trap song, that explores themes of breakup and untrusting love relationships.

A music video, shot in the desertified surroundings of Los Angeles, and in a forest outside Fresno, California, was released on August 26, 2016, and displays, though a "cinematic" and "dark" atmosphere, a "mysterious" storyline about Brown following his ex-girlfriend to a foggy club that ends up being full of vampires.

[3][4][5] On April 27, Brown announced the mixtape Before the Trap: Nights in Tarzana, the European leg of his One Hell of a Nite Tour, and the release of a new single on May 5.

Lyrically, in the song Brown addresses how his second lover became his main girlfriend, combining passion and romance, but their relationship changed for the worse, ending up in a bitter breakup.

In the track, Brown is wary of the intentions of his female liaisons, while calling out his ex-girlfriend for putting on a false facade to impress others, lamenting that he's tired of texting her, as he sings "I know what you want, but you're not gon' get it (...) You do what you want with somebody else / I'm gone, baby".

[16][17][18] Carl Lamare of Billboard said that the song is "Brown first major attempt at the whole "dark R&B" craze, and it works perfectly" describing its composition as "brutally honest lyrics over a beat that's somber, but danceable".

[10] On August 26, 2016, Chris Brown uploaded the music video for "Grass Ain't Greener" on his YouTube and Vevo account.
