Good question, I could look at doing something like that, not sure how but, I am sure you can easily turn YouTube videos into sound recordings alone, there is plenty of YouTube to Mp3 or mp4 sites. I'll look into it, but for now you can just go to this online converter, drop the link of any youtube video you want in, and you can download the video as a .mp3 which you can then listen to at anytime without even using your data plan.
