@donavabdear would not those natural sounds have harmonic structure? If the bass is not correct, then the sound is not correct. I have a different emotional reaction to what sounds like real thunder versus something that sounds like "fake thunder". One makes me think of summer storms, and rain. The other makes me think of bad EDM.
Perhaps another bad analogy. Do you ever go watch cover bands. The ones that try to mimic the original, will always be judged against the original, and if you can't do a reasonable Angus Young guitar rift, you will never be a great AC\DC cover band. Your brain can't not compare the original to what you are hearing. Compare that to a cover band that tries to make songs their own and not replicate the original exactly. It is often easier to enjoy those because you are engaged in the music, not engaged in a continuous comparison.
