Not an immediate answer to the question but I doubt that you need to put these podcasts into your reference list at all. It depends on what you mean with "analyzed" and the customs in your field.
To me, "analyzed" indicates that the podcasts are your primary research material rather than something that you want to refer to because you reuse or report specific results, ideas, or concepts from another publication. In that case, it may be more appropriate to describe the details of which podcasts you analyse and where you got them from in the text only, maybe also with a dedicated table that lists the titles / publication dates / links for each episode, but not include them in the reference list.
However, what is customary in that respect differs by discipline, so I would recommend to ask your supervisor whether you should put these as citations in your reference list.
