There's a whole page of German radio here - http://www.listenlive.eu/germany.html - (I think my German student uses this, and there are a huge number of stations you can stream/download, so go nuts). For Deutsche Welle in German, look for the 'Deutsche Welle' link, with the 'in German' description, click on the stream link next to the little icon that looks like a diamond with a yellow thing (this (http://www.listenlive.eu/dw-de.m3u) is the link) and it should open in iTunes as a continuous track and will begin playing. I tried going to their website but I just got German news in English.

You can also try going to iTunes, clicking on 'Radio' in the sidebar, choosing 'Talk/Spoken Word', going to 'Deutsche Welle' and selecting the one with its description in German.

I'm sorry those instructions are so long. And you need to have iTunes for both of them, which is unfortunate if you don't.
