Featuring the vocal collaboration of Puerto Rican performer Daddy Yankee, it was made available for digital consumption on 8 June 2015 through Roton, Fonogram and Global Records.

An accompanying music video for the single—directed by Khaled Mokhtar, Dimitri Caceaune and David Gal in both Romania and Puerto Rico—premiered on Stan's YouTube channel on 8 June 2015; it portrays the singers residing in a party hall.

"We Wanna" was promoted by various live performances during Stan's concert tours that supported Alesta, but was also sung in a stripped-down version for Romanian radio station Pro FM.

[15][16] Music website Pop Shock felt the recording leaned "more towards Alexandra's recent output than Inna's heavier dance sound.

[16] Bradley Stern from MuuMuse felt "We Wanna" was a "super solid, club-ready summer jam bound to blow up from Argentina to Morocco, full of catchy hooks ('Bout to go!')

"[22] He eventually found Stan and Inna outperformed Rihanna and Shakira, and Lady Gaga and Beyoncé, who previously formed female duos.

[19] German portal Hitfire was generally positive towards "We Wanna", explaining that its "verses are disappointingly quiet until the chorus turns up something.

[37][38][39] The visual was shot in Puerto Rico and Romania by Khaled Mokhtar, Dimitri Caceaune and David Gal, with whom both Stan and Inna had collaborated with in the past.

[5] The video opens with Inna answering to a call she gets from Stan on her Lenovo smartphone, of which the ringtone is the saxophone riff featured in the song.

The next scene portrays Stan and some backup dancers hanging out in the dressing room of a club, with her eventually going downstairs to the full party hall and later meeting Inna there.

[19] Website Hitfire explained that the music video revalued the song, further pointing out the absence of a plot, but naming it "worth seeing".

[42] They further sang a stripped-down version of the recording for Romanian radio station Pro FM on 9 June 2016,[43] while additionally uploading a video on Stan's YouTube channel that sees them performing the song live at Parcul Herăstrău, Romania.
