As a former human King and the current King of the Land of the Dead, the Skeleton King had ruled for centuries. It was only natural that he knew music.
His position had surrounded him with Royal Nobility, exquisite food, rare treasures in the Royal Palace, and performances by the finest opera singers.
Even a farmer would develop an exceptional ear after decades of exposure.
The more Annan thought about it, the better the choice seemed. He just needed to ask whether the Skeleton King had time.
Annan opened a Teleportation Portal to the Land of the Dead. Waiting to receive him was an old acquaintance he had not seen in ages: Madam Puppet.
After Annan explained what he wanted, Madam Puppet said he had come to exactly the right person. Even now, the Skeleton King still played a piece now and then.
"What does Mr. Skeleton King play? It can't be percussion, can it?" Annan joked, only for the man himself to overhear him.
"If you can hear my voice, why wouldn't you be able to hear my music?"
Annan went as meek as Cathy when Mr. Swaro caught her.
"Do you have time?"
"What do you need me for? Do you want me to compose a theme for your Magic Film?" Soulfire flickered in the Skeleton King's eye sockets.
"Something even more important. I'm holding an Opera Singer Contest..."
Annan explained it all again. When he finished, the Skeleton King murmured, "Interesting. I'd be willing to serve as a Judge."
"That's wonderful!"
That made all five judges: Annan himself, Falu, Bailey Knight, a Siren, and the Skeleton King. They represented the organizer, the living, the Academy, Foreign Races, and the dead.
Annan did not know whether the lineup carried enough weight, but no one could accuse "Everyone's Singer"
