Pretty good radio player, if you only want that. Nowadays most media players have online radio support integrated, but it's never they're main purpose and sometimes doesn't work that great. Contrary to that, "Radio Sure" is an application only dedicated to radio listening, it has good features, like the ability to record what you listen, has a decent equalizer, volume normalization, skin support and more. Works flawlessly and runs low on resources. And hey it's free! Give it a try.

Even though the radio stations list in the RadioSure sometimes not updated, we can still manually add radio station to the program by getting the playlist (.pls) from our favourites radio station, copy and paste the URL from .pls, add a title and create a new station in the program. Hence, it shouldn't be a problem to listen to the latest radio station out there through this program.
So, for me, I think it is still best online streaming radio program with simple interface and easy to use.
