"In the Ayer" is the third single from rapper Flo Rida's debut album Mail on Sunday. It was produced by and features will.i.am. Tiffany Villarreal performs the background vocals, but she is uncredited (credited as Fergie in other countries) . The song's backdrop and beat are sampled from Pretty Tony's freestyle classic "Jam the Box", which is not credited. The song has been certified platinum by the RIAA, making it his second song to do so.
The song was recorded by Pardraic Kerin and mixed by Dylan "3-D" Dresdow.
The official remix features Rick Ross, Brisco and Billy Blue with original chorus by will.i.am and new Flo Rida verses.
A year before the song was released, will.i.am was at Los Angeles's KIIS FM (102.7) doing a freestyle for Jojo Wright over the instrumental of "Easy" by Paula DeAnda. He described the freestyle as a "hot hook". The beat production was done by Timbaland with the help of DJ Tweak from Lakeland, FL.
