On August 13, 2013, T-Pain premiered "Up Down (Do This All Day)" (originally intended as the first single from his fifth studio album Stoicville: The Phoenix). The song featured production by DJ Mustard and a guest appearance from rapper B.o.B. It was then released to iTunes the same day. Mustard's production is bouncy and synth based, with heavy use of the Roland 808 drum machine.

In the song T-Pain professes his love for strippers and liquor. Rap-Up referred to the song as a strip club anthem. T-Pain spoke on the song saying, "You know I'm the strip club king. It just goes like that, man. Basically, I'm just making another one. This is regular shit for me. I'm just going in!"

T-Pain told Artistdirect about the song's creation saying;

"It started with the beat. I was listening to the beat for about three days. Once I forced myself to do it, then I had it. It wasn't really a hard thing to do. I was just like, "Alright, I guess I'll do this one! Here we go!" You know, I've been working with B.o.B since before he got signed really. It's been a good time. It's been really collaborative with us. At the time, it wasn't the right songs or the right situation. Now, that I had something good so it was only right. I don't make people conform to what I'm doing when I got to get somebody. When you get T-Pain, you don't really want to tell T-Pain what to do. If you got in mind what you want T-Pain to do, you could've done it yourself. That's where B.o.B came from, and he enjoys strip clubs as much as I do. It was only right to get him."
