When you refer to the agent/manager, are you referencing the artist’s agent/manager? Keep in mind, from a close-minded point of view, this could look like extortion or intimidation. (akin to “Release it here or someone else will”) And I certainly would not want to start off on the wrong foot. Especially with a technology that could basically become the holy grail for the music/art industry.
Dealt with correctly, this could be a powerful adoption mechanism.
