@markv,
I don’t listen to internet radio much. I just tested it out and I see a couple presets from my local area were still present and working. However, it was a mess when I tried to browse for stations. First, there is a list of countries to browse from and the US is not one of them. If I browse by genre I get the usual suspects, classic rock, 70s hits, 60s hits, etc. Some worked and some didn’t.
Overall, I would not base your buying decision on the 851N radio streaming capability. Just install TuneIn Radio on your phone, use the 851N bluetooth (which is quite good), and be done with it. I don’t know why they bother with curating their own stations. It’s already been done much better by others.
FWIW, I did listen to streamed stations at 128 kbps and sounded very good.
