Jody, your BB recordings are hands down the BEST! I listen to your 30-minute power nap recording a lot (a way lot). Fabulous.
Just a suggestion: It would help if you changed that “all-done ding” to something less startling… perhaps a series of dings that gradually increase in volume. I about fell on the floor the first time I heard it (LOL). Regardless, I’m used to it now and actually anticipate it, such that my eyes automatically open a few seconds before the bell rings (like Pavlov’s wife 😆).  
Keep up the great work!
P.S. You should have named this video, “What are binaural beats? Are BBs BS?”
Awesome, I'm glad to hear it!
And yeah, if YouTube allowed me to replace the video files (instead of having to post new ones) I would definitely implement a gradual alarm sound.
