It's only dawned on me recently that quite apart from the various Radio Apps the easiest and generally best way to access any of the 38 radio stations on offer is to simply press the mcriphone button and say 'Radio' - or even BBC Radio 3' or whatever station you want to listend to.
This is not or does not appear as an app and so some of you may have missed it but it's incredibly easy to navigate and switch between stations. I don't think there's any way into it other than by using the microphone but that isn't really a problem at all since it works so well.
Hope that helps a few of you find a quick and easy route through to the radio stations and one that is not, as far as I can see, listed as an app.
I also noticed yesterday that the Sounds App seems to have been up graded so that on the Virgin (and Fire TV sticks) the options to rewind, forward wind, go back to start and go straight to live. Just like the iPhone/iPad. I'm sure they weren't there before!!
