I do that too, but no more audiobooks—now it's radio music (WDR4) or current affairs programs (WDR5), all via the internet because I live in the Netherlands. Another alternative is the daily soaps on ARD or, on Sunday evenings, the "Herzfilm" on ZDF. All via the internet.
A nice talk show is good too, like Kölner Trepp or Plasberg. Both on WDR television.
Of course, the pattern can't be too complicated then.
Well, I have to get back to work. In the next few days I want to present my own webpage, and that still takes some work. When the time comes, I'll announce it.
