I think Megalovania is Genocide Frisks theme. Here is the reason.

In a boss fight 2 kinds of themes can play. The first is the classic characterization of the boss. The theme suits the boss. Examples are Heartache, Spear of Justice, Death by Glamour or Bergentrückung.

The second kind does not belong to the boss, but rather should support the player. Hopes and Dreams does not belong to Asriel, but to Pacifist Frisk. It is the theme of the player in this fight.

In Undertale we now have 2 special fights. First the fight against Undyne the Undying. It's her theme, but the theme should motivate her to stop the player. So it's like Hopes and Dreams, but for the opponent. It is the theme of a hero who fights the pure evil.

The second fight is against Sans. Here Megalovania is played. This song is traditionally the theme of the power-mad final boss. And that is clearly not Sans. Here, Undertale simply turns the classic gameplay principle by 180 °. It is not the player who fights against the game, it is the game who fights against the player in the form of Sans. The game wants to stop the player before he destroys everything.

So you do not have to look at this fight from the perspective of the player, but instead from the perspective of Sans. He fights against the final boss. And Megalovania is therefore the theme of Genocide Frisk.
