@ Karemi, simonsimsity etc
I'm one of the Russian providers in Lingq.
You propose interdesting materials, but most of them is impossible to give to the open library because of the 'copyright' (авторские права). It is a bit stupid maybe, but we can free download only works when their authors were died 70 years and more. So I'm not even sure that "Древо поэзии" is legal here though I like these translations.
I can only recommend for advancers to use You tube and other resourses for private podcasts, it's mostly possible to do.
I write also a lot for Lingq my own podcasts and lessons, they are 25% - for beginners, 25% about politics and history, 20% - the stories from the classical Russian literature, what is already free of copiright, but 30% for different everyday topics mostly for intermediate 1, seldom - for intermediate 2 because with this level you can find already a lot of resourcves in the internet.
Who is interested can find my poscasts and collections like "Разговоры с Евгением", "День за днём", "Рассказы о России", стихи Пушкина, Есенина, рассказы Чехова, Гоголя, Достоевского, Русские народные песни и романсы etc.
