Before its official release, it had been leaked using multiple different titles, such as "Stranger" (a preview-only version that used radio tags referencing Avicii in his podcast called "LEVELS", as well as Nicky Romero's podcast "Protocol Radio") and "Nicktim" which was also called "Fuck School" by his fans (a version that used vocals from "D.A.N.C.E." by Justice).
Robert Copsey of Digital Spy blog gave the song a positive review stating:
The person in question is Dutch house producer Nicky Romero, a man who is slightly better acquainted with the current crop of mainstream club poppers, including Calvin Harris, David Guetta and Bingo Players. As such, 'I Could Be the One' is a battle between Balearic-style EDM and squiggly, chart-friendly breakdowns that hit all the right places. The result, predictably, is a peaceful truce. .
"I Could Be the One" has seen massive success across Europe, particularly in the United Kingdom, where the single debuted at number one on the UK Singles Chart on 17 February 2013 ― for the week ending date 23 February 2013 ― becoming Avicii and Nicky Romero's first chart topping single in the UK, On the UK Dance Chart, "I Could Be the One" debuted at number one ahead of Baauer's "Harlem Shake", which entered at number three.
A music video to accompany the release of "I Could Be the One" was first released onto YouTube on 24 December 2012 at a total length of four minutes and 46 seconds. It was directed by Peter Huang and won first prize for non-European music video at the Young Director Award 2013 in Cannes. 
The video stars Inessa Frantowski as a woman who works in an office. She clearly hates her job, her morning routine and her work colleagues attitudes. Next, she is seen waking up in a room next to a used condom and a man in bed with her. When she opens the doors in her room, it reveals a balcony with a view of a beautiful beach. She finds a "To-Do List" in the room, with the only 'job' being to "not give a fuck". Then there are several shots of her enjoying herself: walking down a beach destroying a little girl's sandcastle (while giving her the finger), eating a selection of foods in a restaurant before kissing the waiter and dancing in a club with a man before having sex with him on a yacht. She then wakes up in her own apartment, and all is revealed to be a dream. She sees a therapist, who does nothing but prescribes her "more pills". Back in her office, she sits at her desk listening to her colleagues' mundane conversations. Finally, she loses it and begins to wreck the office, throwing her paperwork around, destroying a fax machine, insulting and assaulting some of her colleagues before fleeing the office. Bursting out the office door, the final scene shows her on her phone, booking a one-way ticket to Barbados. As she runs across the road to her car, she is hit by a delivery van which is labelled 2Late. It is unknown if she died or survived.
