Parallels toolbox is still my go to for this kind of stuff, at some point I’m sure it will get taken off the market but for now. 15 years strong. Still works with YouTube and Twitter.

podcasts

I had to spend ~1 hr doing this for a funeral *music* playlist and @NunyaBidness shared this for podcasts. 

tbf the hardest part of the music version is you have to own the music to modify encodings, and podcasts are mostly free, but I'm a fan of single purpose tools like this anyway.
