I am an avid listener of YouTube essays during the work day.

My usual go-tos
Jeff Gerstmann's Ranking of NES games
Retro Pals Stream archives
Random Stranger's series
Uwos Labs videos (if I'm feeling spicy)\
EXP

May also have friends' streams on if they are live

On certain days I usually have specific things going on
Tuesdays - The Nextlander Watchcast
Wednesdays - The Jeff Gerstmann Show podcast
Fridays - The newest EXP Firearm Experts reacts
Saturdays/Sundays - The newest Jeff Gerstmann NES Ranking
