Just finished watching your show on Covid19. As always so informative. I love all of your programs but I wonder if you ever watch them yourselves. The background music is terrible. Very high pitched and so loud that it interferes with the speakers. I always have to use closed captioning when watching. Noticed many docs like that with awful background noise. Why does this happen? Can it be fixed? Does anybody care? Thank you for all that you do and thank you for letting me express how this loud music detracts from the meat of the show.
