How do various artists (and their lawyers) react to Dougs use of their songs?
Because Doug occasionally plays the music in his helmet on its external speakers, his use of it can sometimes be viewed as a “public performance”. As a result, Doug (when at home, at least) assiduously pays the appropriate fees to the various music licensing agencies (ASCAP, BMI, etc.) and provides them with logs of his song usage, just as though he were a radio station; the fees he pays are somewhat lower than a real radio station would pay, but even so are not insubstantial. He’s done this from the beginning of his career as a Warrior; having grown up in the entertainment industry, it seemed to him like the only fair and proper thing to do.
