yep, in cycle 4 delta sleep a commercial blasted in my ear lol..... but good overall
Hey Dale! Sorry that happened to you but glad to hear you were still able to get a good sleep despite being woken up by an ad. For the record, I do have the video set to NOT show any ads but YouTube has become VERY aggressive with their advertising settings and ultimately they do whatever they want. 
I am currently offering this track for "pay what you want" pricing if you'd like to give it another try directly from your device with zero advertising. https://bit.ly/sleep-101
