Podcasting is highly developed in the realm of language learning and although a lot of good content comes at a premium, also a lot is free. If you search 'learn nn through podcast', especially when nn is a rather commonly used language, you will find an astonishing amount of productions. Many are very similar and most of the free content is on beginners level, but through a couple of sessions of initial listening you can certainly identify the podcast that matches your level and preferences.
For example pick up some French. Here is a quick sample of what I collected when I was looking for a refresher of my high school French:
