@YouTube please implement an “I’m sleeping” feature to your site where I can listen to soft music or asmr without loud ass midroll ads that randomly blast like “THE DODGE 12000 IS THE NUMBER ONE RANKED VEHICLE BY KELLOG”. I don’t care about ads. Just make them quiet. Please. 
This isn't a feature yet. However, you can always tell us what features you'd like to see by tapping the 'Send Feedback' button: https://yt.be/help/RXTc . This will help us prioritize the request, thanks!
