Goodbye Rainbow Road

"Hello Rainbow Road" is one of the earliest songs in Centaurworld, and is the one Horse uses to convince the Herd to venture outside of their comfort zone. A short reprise of it is found in "Who is She (Reprise)", where Horse has completely lost hope due to forgetting the face of her friend, as well as her body slowly changing over the course of the show, and essentially tries to kill herself by jumping into the Whaletaur Shaman's mouth.
