A: Could you stand to do a bunch of writing-for-exposure, beyond what you’ve done, or would it be too soul-killing? That mercenary shit is so much a part of the literary landscape now. I don’t know. Nonfiction is the price of fiction.
Similarly we wish it weren’t necessary for rock songs to be used in commercials, but... that’s the way it is? I don’t know if that’s a valid analogy. Economies of attention are what we’ve got, though.
B: I think the analogy is not licensing your song to a car commercial, which no one minds any more, but having to go spend two weeks of every month busking at the auto dealership.
