I am finding this more and more common place on my commute. I chalk it up to the Bluetooth headphone push/ loss of the aux. People either don’t have headphones now or their Bluetooth ones are dead. I just resort to putting my headphones in, maybe make a bit of a show of it in hopes that they see me.

I believe Jdownloader 2 lets you do link grabber with YouTube links that can download audio only with a choice of format.
