The lyrics are heavily inspired by Sigrid's experience as a young woman in the musical industry and situations people her age might encounter.

The title track and "Dynamite", which first appeared in the EP, were later included on Sigrid's debut studio album, Sucker Punch (2019).

"[6] Sigrid was paired with Norwegian producer Martin Sjølie, and together they finished the demo of the song "Don't Kill My Vibe" that was sent to Luedy.

[6] In September 2016, after executives heard that demo, Sigrid signed with Island Records and continued working with the rest of the EP.

[2][7][8] The title track, which was originally a piano ballad, was reworked when Sigrid and Sjølie thought the song needed "[more] production" after listening to the chorus.

[9] The lyrics were described as "intensely relatable and wonderfully frank," which are inspired by her experience as a young woman in the music industry and situations people her age might encounter.

[1][9] Abigail Hyland of The Line of Best Fit wrote that the EP "[vocalises] a problem that's been festering at the core of the music industry since its beginnings; for too long female artists have been subject to manipulation and oppression from men in positions of power".

[15] Don't Kill My Vibe opens with its title track, a melodic electropop anthem inspired by a difficult session where Sigrid felt her voice and opinion was being diminished.

[39][40] Jason Lipshutz, writing for Billboard, summarised the EP as "13 minutes of spectacular songwriting, four songs full of immediately charming hooks that wind their way toward bigger, more perfect choruses".

[14] James Barker of The Edge praised Sigrid's vocal performance and concluded that "there's little to criticise on Don't Kill My Vibe other than its pitiful length, but hopefully the Norwegian star-in-the-making will be back very soon with more gifts for her big pop breakthrough.

"[41] Abigail Hyland from The Line of Best Fit applauded its feminist lyricism, especially with the title track, which she felt that gave "female listeners [...] an anthem to get riled up on and effect change in their own lives.

"[15] Commercially, Don't Kill My Vibe spent one week on the Billboard Heatseekers Albums chart, peaking at number 19 in June 2017.

[20] Zara Hedderman, writing in a review of Sucker Punch for The Irish Times, opined that the EP's popularity made "Sigrid [emerge] as a relatively unknown singer, outside of her native Norway, to become the name dropped into conversations with music-savvy friends, as though she was your discovery.
