Not everypony likes colt bands. But Twilight has always loved them. So when she gains her own castle, she turns one of its rooms into a Chamber of Colt Bands.
Will she be able to inaugurate it without any unpleasant surprises?
Written in about half an hour due to writer's block and boy band music. Dedicated to all people (and ponies) who love (or love to hate) boy bands.
Also contains some implied FlashLight.
