I'm not sure what the Norwegian band Pom Poko has to do with the Studio Ghibli production if anything, but I could see their music fitting in nicely because they're quirky and fun. They've got a handful of singles out now, and the best of those in my estimation is today's Most Important, "You'll Be Fine", a sweet love letter to yourself.
