To be fair, Mastodon is creating music specifically for Pixar, for the new Monsters movie. I don't think they're just sandwiching (samwiching?) their hits into it after signing a lucrative deal. It could suck, sure. We could get a horrible live action - animation synthesis set to the credits while they croak out violent lyrics. Pixar is still a giant force of creative geniuses that have made films that could stand the test of time longer than the Disney classics of yesteryear. They have the integrity to create lasting products other studios lack. I have confidence.
