[1] Written by Carey, Jermaine Dupri and Johntá Austin, and produced by the former two and LRoc, the song samples the hook from British band Imagination's "Just an Illusion" (1982),[2] and derives its production from "‘80s-esque synthesizers" and several computerized musical instruments.

"[6] Aside from her signature vocals, Carey adopts a breathy rap for parts of the song, which read "I got a pimp penthouse / With a sick hot tub / We can watch a flat screen / While the bubbles filling up.

The Guardian editor Caroline Sullivan outed "Stay the Night" and "Get Your Number" as "the first Mariah Carey tunes in years I wouldn't have to be paid to listen to again.

"[7] Barry Walters from Rolling Stone complimented her vocal performance, writing "Carey's belabored voice finds a pleasurable medium", however criticizing the song's production.

[9] Jim Abbott from the Orlando Sentinel described the track as a "sexy, slinky dance number", while a writer from Newsweek claimed it to be a song that "worked".

[22] It was filmed in Los Angeles on September 1, 2, 12 and 13, 2005 and features Jermaine Dupri as the video's secondary artist, while Michael Ealy, plays Carey's love interest at the club.

The next scene finds Carey sitting on a large pink sofa in an empty room in the club, sporting only a white man's suit jacket and stilettos.

As the song reaches the bridge, Carey is shown back in the club's main room dancing, as she leaves a number '4' on a nearby table for the man to find.

As Carey once again is shown in the yellow latex dress, she walks down a small aisle, placing another card with the number '4' into Ealy's jacket pocket, before storming through the club by several followers.

As the video ends, the number '555-6464' are shown lying on a small table, while Carey sits on the large pink sofa, and Ealy is seen on the other side gazing at her.
