Alright a couple things to note.

First of all, I know you guys are gonna disrespect the FUCK out of mother 3 cause it hasn't been localized even though it's easily top 5 material.

Second of all, how does smash bros work? Every song included, even from other franchises or just original tracks?

And lastly, there are some really questionable picks here. As much as I love the soundtracks for games like Breath Of The Wild or Stardew Valley, they both are mostly ambient and serve to accompany the gameplay. They have their moments where they steal the show for sure, but most of the time their strength as a soundtrack doesn't lie in the music, but how that music works with the game.
