Incorporating pounding drums and shimmering synthesizers, "Ass on the Floor" was praised by critics as one of the best songs on Last Train to Paris.

An accompanying music video, filmed by Colin Tilley, has a cold icy theme and features the female members of Dirty Money taking the lead as the group poses for the camera across the winter wonderland-themed landscape.

"Ass on the Floor" is an atmospheric dance-floor filler, first released as part of Swizz Beatz' Monster Mondays on November 29, 2010.

[4] "Ass on the Floor"'s production also consists of "pounding drums" and "glittery synthesizers" whilst the vocals focus primarily on Diddy-Dirty Money's two females, Dawn Richard and Kalenna Harper.

[5] Jamie from Freshness said "With 'Ass on the Floor', the group not only opts for a heavy club vibe in terms of titling, but in sound as well... [which includes a] decisive marching beat".

Zeigbe said "The vibe of the song definitely stays on track with the naked emotion the Bad Boy mogul promised on the trio's long-delayed effort, Last Train to Paris.

[9] In the "winter wonderland"-themed clip Richard and Harper take the lead while Swizz Beatz and Diddy make background appearances.

He said "[the] somber dance jam 'Ass On The Floor' and its frosty visual are proving that old adage that third time’s a charm, [referring to the third video Diddy had released that week].

[9] Dirty Money made their debut performance of "Ass on the Floor" on the December 4, 2010 showing of Saturday Night Live.

[14] American songwriting and production duo The-Dream and Tricky Stewart were commissioned to produce an official remix for the song.
