Podcasts and similarly structure long vids are a fantastic source of low-maintenance entertainment for me. I usually get a good idea of what I'm listening but only very specific subjects would I actually give priority as to avoid multitasking, and would be so because I want to squeeze the knowledge or ideas being conveyed. In most cases though, my atention span is far too limited to swallow a podcast without doing something else on the foreground. Because of this a podcast can be about anything I find interesting, from roleplay and literature to even philosophy.
