One difference between a house and a recording is marginal cost of replication/reproduction: not zero in case of a house, effectively zero in case of a recording.
Without a government granted monopoly on copies, the marginal financial value of a copy is close to zero in all but the most exotic cases.
With a government granted monopoly comes a real cost: enforcement, and loss of social value. How does one justify that?
Authors' descendants do not have a $DEITY granted eternal right to exploit the author's work, and rightly so. This is why "intellectual property" can be more accurately described as "intellectual rights".
