There's a Facebook group called "Audio Pro users". In there, you can find APControl, a small utility for Windows that lets you save and playback any web radio stream, not just TuneIn's. This is most useful for people who have a Windows box on at all times, especially now that TuneIn has restricted the number of available streams in the UK to UK-based radio stations only.[...]
It really seems to be a great speaker for the money... but there is one (fairly niche) thing that I didn't think of before buying. I thought I'd post here as it might be of some use to some people out there
In the UK, the BBC opted to remove all of their radio stations from Tune In. If like me, you generally listen to the BBC suite of stations, the preset buttons on the top of the unit aren't going to work for saving your favourite station. You can only save stations from the supported online services. BBC Sounds and Radio Player aren't supported (at the time of writing at least).
