[Record of Funk] Up-Incoming Rappers

This Track replaces "Shop"

Leitmotifs: "Start Screen (Itch.io Build)", "Give a Lil Bit Back"

I thought something more akin to “Hip Shop” fits FNF more than “Shop”’s feel.

[Record of Funk] Give a Lil, Get a Lil

This Track replaces "sans."
This is Skid and Pump's overworld theme after their battle at the end of snowdin's replacement.

Leitmotifs: "South"

Skid and Pump are pretty much never seen apart, so having them take the "generic" versions of sans and papyrus' roles would mean that they'd spend a weirdly out of character amount of time away from each other. 
So, in this AU, they both share the roles of Sans and Papyrus. (This means that both skid and pump will be present in almost every given scene that either sans or papyrus were in, regardless of if both the skeletons were there or not. Ex: Papyrus' Date or Sans' Grillby's scene)

[Record of Funk] From Down South

This Track replaces "Fallen Down"
This theme is more-so for GF than DD, despite him technically being the Toriel role.

Leitmotifs: "Bopeebo"

Daddy Dearest replaces Toriel only in the sense that he's the first boss, he doesn't like or care for BF and instead, actively wants him dead. Daddy Dearest is the reason for most of the encounters in the AU, as he puts a pretty hefty bounty on BF's head after losing his battle against him.

[Record of Funk] Show-Off Showdown

This Track replaces "Oh My..."

Leitmotifs: "Lunchbox", "Lunchbox Scary"

Senpai replaces Mettaton, of course, while Spirit replaces Mettaton EX.

As Hating Simulator isn’t an actual location, all of senpai and spirit’s appearances/encounters occur through being sucked into Hating Simulator at specific scripted events whilst traversing The Wastelands. 
The closest example is probably a moderately more common version of Rouxxls Kaard’s appearances in Chapter 1 of Deltarune.

[Record of Funk] Gun's March

This Track replaces "Nyeh Heh Heh!"
This is Skid and Pump's overworld theme prior to their battle at the end of snowdin's replacement.
(FINALLY I'VE LANDED ON A VERSION OF THESE TRACKS I LIKE)

Leitmotifs: "Spookeez"

Skid and Pump are pretty much never seen apart, so having them take the "generic" versions of sans and papyrus' roles would mean that they'd spend a weirdly out of character amount of time away from each other.
