It's not uncommon for podcasts to feature author interviews about books, it would make sense to be able to link to the works for these type of interviews.

 

Additionally, I have added a number of audio documentaries. For example,

It's not clear how to link these to the documentary subject. Tribute is obviously inappropriate, but dedicated to also doesn't feel quite right (documentaries may not always be positive after all). Perhaps a commentary on artist relationship would make the most sense in these cases?
