Hi Andy!
I realize it is not exactly what you asked for, but I can report finding great enjoyment and success with the TuneInRadio Pro app in the last year. It is effectively an Internet radio receiver for your Android or iPhone smartphone, PC, or Mac. There is a free version as well as one at modest cost, available from the Google PlayStore as well as iTunes. I have it installed on all my devices.
So you won't have to hunt for them, here's some direct download links:

I found a few stations I enjoy also listening to now I'm home, among them several in Romania and a couple in Serbia and Hungary. A number of broadcasts are also available in English-language if you aren't a native speaker of the local tongue where the station is located. In use, behavior is much like a pre-tuned shortwave radio but focused on commercial radio stations and podcasts. Sound quality is exceptionally clear and it allows pausing of live broadcasts.
Demand on data connections seems to be pretty slim for a streaming app, but you should check usage if yours is metered. On wifi, there's no problem at all. There's a number of other, similar services I've tried and enjoyed, but TuneInRadio is the one I find myself returning to most often for live broadcasts and podcasts.
Best,
Dan.
