Neon Jungle got together with English singer-songwriter CocknBullKid and British electronic band Fear of Tigers to develop "Trouble".

[3] In an interview with Lewis Corner of Digital Spy, Amira McCarthy described the song's development process, saying, "I think we just went into it with a positive attitude.

"[4] The song was written with the intention of showcasing the band's fun and youthful side, in addition to having a raw and chaotic sound.

[8] The remix was honed with positive reviews from contemporary critics, Sam Lansky of music website Idolator wrote, "'Trouble' gets reconfigured as a club-ready dancefloor banger, all video game bloops framing that irresistible 'I don't look for trouble but trouble looks for me' hook before it collapses into a tangle of electro snarls.

"[8] A teaser of the song and its accompanying music video was released online on 12 July 2013,[9] The same day the full version premiered on Heat Radio.

[22] In contrast, the band has explained that listeners should not take the song literally as it's promoting concepts of fun and youthfulness, and not the general idea of trouble.

[3] Bradley Stern of music website MuuMuse highlighted the verse "People say I'm heartless, I just learned to use my heart less / I go hard 'cause I'm hardest and we ain't even started!"

Digital Spy's Lewis Corner awarded "Trouble" four out of five stars, commenting, "'Trouble' packs a punch hard enough to make you stand up and take notice.

"[21] Corner further noted that the song has "a hook that draws you in and fiercely defies you to let go," concluding, "as far as first singles go it's little less than a triumphant piece of pop.

"[21] Jim Carroll from The Irish Times praised the song, describing it as "a wham-bam, day-glo blast of pop sass, energetic high jinks and sticky-as-chewing-gum hooks.

[17] Loud Magazine's Emma Austin positively reviewed the track, writing "Punchy, poppy and guaranteed to get stuck in your head.

"[8] Lansky went on to opine that the song has a freshness to it which he described as "invigorating" and a "gleaming shot of electrogrit built around the most marvelously nasty hook.

"[9][20] He concluded his review, commenting, "['Trouble' is] a summer smash, a dancefloor filler, and the kind of enormous, we're-here-deal-with-it introduction that all the best UK girl groups have had.

In his review, Stern added, "The song's full of big, bold brags along the way, but it’s really all about the chorus, which is repeated endlessly — but at least it’s a damn good one."

"[26] A writer for music website Popjustice deemed the song "one of the smartest and most unusual debut singles in recent girlband history".

[31] Speaking to Andrew Bloss of the Croydon Guardian, Plummer explained the group's excitement with regard to the single's chart performance, "I can’t believe we have 5,000 followers on Twitter, we only came out two months ago with no one having a clue who we are and we still made it to number 12.

It was directed by Emil Nava, who Neon Jungle enjoyed working with, the group said that he was "crazy" and that "you can't not have energy with him 'cause he'll just bring it out of you.

[36] A journalist from The Guardian mentioned, "The video for their first single, 'Trouble', is filmed in a nice detached suburban home in a leafy street to show how they've come to besiege such safe middle-class environs.

"[24] Group member, Plummer told Anna Hughes-Chamberlain of Hunger TV that shooting the music video was the most surreal thing that has happened to her, adding, "I woke up in my own bed and was like, 'was that a dream?

[20] The music video is labelled with requirement of Parental Advisory, and starts out with individual shots and scenes of each Neon Jungle group member.

Stern added, "Unlike some of their competition, Little Mix and The Saturdays, Neon Jungle steer well clear of the clichéd coordinating outfits and choreographed routines and instead, just as the Spice Girls did, actually inject a bit of personality into their brand.
