I am in agreement with the core of concepts posted here. But, why do the producers of videos think that loud audio-drowning music is a good idea. All it does is make understanding the audio difficult and in many cases impossible. Also, in the same videos many speakers use a subdued volume of voice which adds to the problem. As a case in point, I was able to understand about 50% of the video dealing with afterlife. Perhaps a version with subdued music and higher voice volume could be posted so that I can hear the other 50% of the audio.
