I recently discovered that I can save YouTube videos (live concerts, etc.) in .mp4 format using an OS X app called Airy. There are several other ways to do this as well for Mac and PC. I copied the .mp4 files onto a Lexar 32 GB USB drive. They are all listed in good detail under the Gallery icon. Like on YouTube, they play in small or full screen (use the toggle button at bottom left of screen) and if the source audio quality is good (example Steely Dan Plush TV), you won't be disappointed. Why watch video in the car? To pass the time while charging, waiting for someone, etc. One safety caveat: video is blocked and audio continues while driving, but when you stop for traffic, etc., the video kicks in again until you start driving again. So if you are more interested in just the audio from YouTube and being able to listen safely while driving, use Airy to save as .mp3 instead. Airy is a one time cost of US $20. I have no affiliation with Airy.
