The best binaural beats clips on YT.
Great visuals with the sleep videos.
I use 8hrs; both 90 mins Deep Sleep; all Power Naps; Wake-Up. 
Invaluable for the irregular hours of the gig economy.
Your explanatory videos are a welcome addition.
How about a Dr. Greger-style series in Binaural Beats research?
One day, with a team and a budget, for sure! :)
Thanks for sharing your experience!
