Brief descriptions/genres definitely recommended. Please don't be afraid of being :LIB:, I feel like so many podcast recs on this site focus of Political Pods which while fun, I can find myself listening to audio content for 6 hours on some days and I don't always wanna blast politics into my ears, and I know a lot of other people don't either.
I'd say probably like anything below 100-150 is likely to either be half baked or have really shitty unfunny bits, or both.
After that I think its probably best to see if theres a topic thats already slightly interesting to you and start there.
Starting from the most recent is also isnt a terrible idea cause there arent that many running gags or references usually, or they go by fast and dont occupy a ton of time, their relatively recent MKULTRA series is pretty indepth.
