These are the ones I listen to the most, I think all of them are weekly

• secretly incredibly fascinating. They talk about a simple topic and expand it with a lot of trivia and the hosts are very funny.
• 99% invisible. Mostly about architecture that you don’t notice but they give a lot of cool info (lately some episodes get off topic or I simply don’t like them but they have a huge archive that I listen to)
• my brother my brother and me: just stupid comedy from 3 brothers giving "advice"
• dear Hank and John: the brothers Green giving science-ish advice
