An accompanying music video, directed by Mr. X, shows the artists performing choreography in a club in front of blue laser beams.

In light of this, Usher was told to record a few more tracks, and so he enlisted Lil Jon to aid in musical production.

"[5] Several months prior to Lil Jon's involvement in the production of Confessions, he was commissioned by Jive Records to produce fifteen tracks for Mystikal.

The rapper would only select two tracks, which provided Lil Jon the opportunity to give leftover songs to other record labels.

Without Lil Jon's knowledge, Jive Records gave one of the leftover tracks to Petey Pablo which would eventually become "Freak-a-Leek".

However, Lil Jon, assuming that the song had not been used, gave the production to Usher, resulting in a rough version of "Yeah!".

"[6] Lil Jon jumped back in the studio and created an equally catchy replacement track.

By the time they got back to business in January, the record already had thousands of radio plays with no label involvement.

Usher still opted to go with "Burn" as the lead single as a music video was already planned,[8] however, the responses to "Yeah!"

[13] Entertainment Weekly's Jem Aswad found the song to contain crunk and transition between hip hop, soul and ballad genres.

[14] The song was co-written by Sean Garrett, Patrick "J. Que" Smith, Ludacris, Robert McDowell, and James "LRoc" Phillips.

was an uncomplicated song about flirting with girls in a night club; it left plenty of air-conditioned space for Usher to coo and for the producer Lil Jon to bark the interjections [...] The lyrics were delivered like flashes of light: brief, anxious, and exciting, and perfectly suited to a voice that is long on control and short on texture.

Jem Aswad of Entertainment Weekly called it "irresistibly crunked-out", adding, "the ensuing track glides smoothly between club-friendly hip-hop soul and ballads.

"[14] Laura Sinagra of Rolling Stone commented that the song "creates sensual panic by combining Usher's jumpy attacks with Jon's sublime, frayed beats.

"[19] Andy Kellman of Allmusic described the song as a "crunk-meets-R&B foundation" which features an "instantly addictive eight-note keyboard vamp".

as a "club-rattling" song from a combination of "Atlanta's vibrant music scene", Lil Jon's "insistent beats" and Ludacris' "racy rhymes".

"[18] Cibula stated that Usher's "smoove-ass" singing and Ludacris' presence contributes to the success of the single.

[29] On February 28, the song peaked atop the chart and stayed at that position for twelve consecutive weeks.

[33] The single was certified thirteen-times platinum by the Recording Industry Association of America (RIAA) on February 9, 2024, for shipping 13 million copies since its release.

It remained on it for only seven weeks before dropping out, and was certified 5× platinum by the Australian Recording Industry Association (ARIA) for selling 350,000 units.

When the shooting started, Mr. X recalled Michael Jackson's "low-tech" and "laser-flashing" 1979 "Rock with You" video, and used it as a reference.

They went through photo browsing and phone calling, opting for Destiny Lightsy, a friend of Mr. X, who seduces Usher in the club in a Marilyn Monroe wardrobe to complement the lyrics.

Usher took charge of his ideas on his wardrobe and choreography, with additional routines, specifically the Rockaway and the Thunderclap, which Mr. X learned from Jamaica.

After Lil Jon sprays champagne towards the camera in the laser scene, Ludacris performs his verse.

In the final chorus, Usher again performs choreography in the club, with another scene in the latter setting this time showing a different seductress, portrayed by model Melyssa Ford, walking away telling him to follow her.
