Outside was supported by six singles: "Rock Your Body", "Streets of Africa", "Koni Baje", "Sekkle Down", "Heaven's Gate" and "Ye".

Its production was handled by Leriq, Baba Stiltz, P2J, Jae 5, Juls, Chopstix, Steel Banglez, Fred Gibson, Phantom and FTSE.

[11] Reviewing for Konbini Channels, Daniel Orubo said Burna Boy "effortlessly alternates between highlighting the joyfulness of being African, bragging about his prowess with the ladies, praising his own musical ability, and warning his haters not to fuck with him.

[15] Prior to the release of "Sekkle Down", both artists recorded "Good Time", a track from J Hus' debut studio album Common Sense (2017).

[23] On the house-influenced interlude "More Life", Burna Boy paints a picture of relaxation and in the drum-infused "Ph City Vibration", he pays homage to his hometown.

[24][5] The Jùjú-inspired "Koni Baje" features talking and bongo drums; the song highlights the flexibility of Burna Boy as an artist and has been described as a "tribute to his career and a prayer for himself".

A writer for Native magazine said "Ye" is being viewed as a new anthem because it "embraces the anathema of every self-interest seeking seemingly good-natured Nigerian.

[24] The nostalgic track "Streets of Africa" was recorded over a cartoon-sounding trap beat popularized by American rapper Lil Yachty; the song was produced by Leriq and touches upon themes of love and sex.

[27][12] In the dancehall-highlife track "Rock Your Body", Burna Boy sings about his sexual desire to make love to his lover.

[2] One Tribe magazine applauded Burna Boy for experimenting with different sounds, but ended the review saying the LP lacks "a common theme to piece all the songs together".

[28] Segun Akande of Pulse Nigeria said Outside is Burna Boy's "most personal project yet" adding it is "a deeply expository look at himself and the fears and influences that have made him such a divisive figure".

[24] Reviewing for OkayAfrica, Mayuyuka Kaunda described the album as "easily digestible" and that Burna Boy "offers some striking observations—experienced by many—and asks us to keep dancing throughout our journey with him.

"[31] Victor Okpala of Nigerian Entertainment Today said that from a sonic standpoint, the album is Burna Boy's "most versatile offering that saw him push far beyond the boundaries of his musical dimensions – balancing speed, depth, and storytelling".

[26] Wilfred Okichie said each song on the album "tells its own story and serves a purpose, leaving no room for waste or excess".

"[1] Mellowviews' writer Mutsinzi Eric said, "Burna Boy’s music is delivered like performance arts, it is marked by a heart-felt expressionism and always masked by a non-chalant [sic] melancholy.
