The doctor introduces a very technology oriented society to "music". As is often the case, the first performer they hear is their mama duck... they become obsessed with the doctor. The doctor's ego is way over inflated - he believes that he is worthy of such intense adulation. He considers leaving Voyager to follow a singing career, when one of the planet's scientists recreates the doctor, with "enhanced" abilities based on mathematical algorithms. In other words, the doctor plus musical super abilities. The new, improved model supersedes Voyager's doctor's in popularity on the planet. The doctor gives a farewell performance that truly out shines his previous operatic attempts to a tepid reception. He finally understands that fame is fleeting, but friends are a constant.
