This is already easily solved by using royalty-free music or by licensing pre-made music from numerous publicly available sound libraries online -- with the added benefit of supporting actual musicians instead of plagiarist tech middlemen.
I think you got this wrong. Usually you use one electronic musician to create all the background music (or license pre-existing popular music), and with music AI you make that musician more productive. It is not like non-musicians will even be able to select the bad from the good of the AI output. It takes a trained ear to build functional AI music as well.
Nobody will hire live studio musicians or a symphony orchestra to create background music. Way too expensive.
What exactly am I getting wrong? You insisting that nobody hires studio musicians or orchestras, and claiming that "usually you hire one electronic musician" are both demonstrably false opinions that have almost no relation to my point that background music is obtainable through on-demand licensed libraries.
