How come most the tracks are 30 mins long?

It's not bad, it's very japanese pop/rock inspired (duh) but at least it doesn't sound like it would get old quick.

Agreed, but I truly loved Splatoon 1 music too. These themes are in a different level though. Awesome music, as we can expect from Nintendo.

Salmon Run's music also sounded really awesome from what I've heard of it. Now the only quesion is singleplayer, Splatoon 1 had really great tracks there that'll be hard to beat.

World War III already happened, it was called Callie vs. Marie. 
This will be World War IV!

Necro'd because the game comes out in a few days, and more people should listen to this epic music.

Too bad literally every single video in the OP has been taken down.

Aww. We're trying to hype their game, and they take down videos? Good old Nintendo. 

Disagree. It went from rock-themed to girly pop-themed.

Isn't music in general always a copyright issue on YouTube? its music after all.
