Start Menu

"Start Menu", previously known as "Menu", is the 2nd track in the Undertale Soundtrack. It plays whenever the player is viewing a new file.

A very slowed down version of this theme plays after you view the Pacifist End Credits and gain the option to do a True Reset.

Variations
There are seven variations of this track. The Mettaton variation does not play in-game, and only two of these variations are included in the official Undertale Soundtrack: "Start Menu", and "Menu (Full)", which is heard at the end of a True Pacifist Route before completing the game.

These variations of the song continually add new instruments, related to how many friends the protagonist has made.
