It's simple! Choose some stages in Smash Ultimate and give them each their own 5 songs.
The only rules are that the music should be from the same series as the stage, unless the stage doesn't have a franchise.
Also, feel free to create your own medleys.
For example:
Mario Galaxy:
Good Egg Galaxy
The Comet Observatory
King Bowser
Enter Bowser. Jr!
Steam Gardens
Distant Planet:
Awakening Wood
Pikmin 2 Boss theme
Piklopedia/Treasure Hoard
Pikmin Title Screen/Pikmin 2 Title Screen Medley
Credits - Pikmin
Halberd:
Meta Knight's Revenge
Zero Two
Dark Mind Phase Two
Galacta Knight's Theme
Masked Dedede
