Mayhem of the Music Meister!

The Music Meister, a villain capable of controlling others through song, induces Black Canary, Green Arrow, Aquaman, Black Manta, Gorilla Grodd and Clock King to hijack a United Nations communications satellite, launching it into space after they install a device for him ("I'm The Music Meister"). When Batman intervenes, he orders them to attack the hero, which they do in a dance style reminiscent of West Side Story. His plan successful, the Meister frustrates Batman once more, escaping by forcing his captives to dance towards the rocket blast, leaving Batman to rescue them rather than apprehend the villain. Meister escapes to an empty opera house where, in a reference to "The Phantom of the Opera", he plays the organ to a cardboard audience. Batman tries to capture him on a cross-town chase, as Meister releases the inmates and villains of Blackgate Prison and Arkham Asylum ("Drives Us Bats"). Having heard Black Canary sing about her unrequited love for Batman ("If Only"), the Meister has fallen for her, but not enough to give up villainy, and she rejects him. Meister manages to capture Black Canary and Batman and puts them in a death trap. ("Death Trap") They escape as Music Meister uses the satellite to hypnotize the world with his music. ("The World Is Mine") When Black Canary becomes his slave, Batman tricks Canary into singing as high as he, using the satellite to transmit her sonic scream and break Music Meister's mind control. Batman finally defeats the Music Meister, and kindly rejects Black Canary's advances for a final time. Though Black Canary gives up on Batman, she finds love with Green Arrow, who had also held unrequited feelings for her for the duration of the episode. ("If Only (Reprise)")
