Truth! I was so sick of YT ads that I BOUGHT an app so I can download videos from YT ad-free. Then I learned how to copy those videosto my phone so I can watch or listen to them ad-free.
I create a playlist each day and download it nightly to my PC so I can transfer the videos to my phone each morning. It works pretty well. I use the same software to download audiobooks from YT so I can listen to them on my phone.
