I use Internet Radio and its nothing to rave about. All it will let you do is play a station. That's it. No song info. No start or stop buttons. NOTHING. You just click the station you want and that's it. I have no idea how to make it stop besides locking my screen then turning it back on and hitting the pause button from the lock screen. I'm on the look out for other apps...any suggestions????
I have tried several.
WP8 Radio - very basic but does the job, ad supported
Radyo - more advanced, rich UI, song info with images, but limits the stations you can listen to unless you pay for a premium version
BRadio - the winner so far, many features, some unique on WP (like ogg stream support or a 5 band equalizer), song info as text, clumsy way to import stations (but universal), ad supported
