What is music to a game?

There's audio and video. You need both senses in a game. Music audibly accompanies the game.

It depends on what game you're making. Not all games need memorable music. The Legend of Zelda: Breath of the Wild has forgettable ambient music because of the slow-paced gameplay. First person shooters are that way, too. Notice how dungeon themes and overworld themes contrast in previous Zelda titles.

Mario games are fast-paced. You won't hear the same background music for too long, because you only have a few minutes to complete a level.
