At my work we usually put generic 10 hour nature loops with music playing but nowadays they’re all AI generated and I’m trying to find good long videos (preferably 4-10 hours) of fun music. Doesn’t have to be jazz, just music without too many words. What do you like to listen to when working?
A quick search for post rock should get you going. Russian circles, April rain, there’s a lot of good instrumental rock and roll
