Sounds great! I like listening to those old (radio) plays when in the metro or in the kitchen, extremely relaxing. I still listen to the old stuff of "Three Investigators"
on a rather regular basis (and know quite a lot of people who do) which were very popular in Germany - and actually much better than the original US version.
I do have Musil's
Man Without Qualities and Proust's
À la recherche du temps perdu as well which are, of course, way more demanding and unfortunately don't work as good as an intermediate entertainment - but for longer trips on train or so well worth the experience - although I do prefer reading them instead.
