If you want to sort of skip this to get this easily you can skip songs and use no fail from the options menu in game to 'play' the song.
From the main menu choose 'Play a Show' and pick any song, your instrument/difficulty doesn't matter.
Once the song begins press
and 'Skip song' which will take you voting for the end of the setlist, press
to vote to 'Keep Playing' now vote for the songs in the next setlist and repeat the skipping process for the songs again. Once you've finished the setlist and are at the voting for the next setlist press
to 'End Show' which will end the show and offer you the chance to perform an encore, choose one of the songs (Do not press /Orange to turn down
) You must play the encore out, you cannot skip this one but with no fail you can ignore it.
