Focus feature for Live Radio?

It would be very nice to have a Focus-like utility that would operate on the Live Radio submenu. Right now there are built-in choices for language, distance from the user in miles, and/or genre, but all of those and more could be combined into a Focus menu that would allow users to slice and dice the entire Live Menu. Look for streams above 320? Done. Look for Dutch language '60s garage band streams? Done. Look for German language classical Baroque streams in FLAC? Done.

The Live Radio streams have grown and grown in both number and quality. It is difficult to wade in and explore without having some handle on the choices available. (just type it in your browser) is superb, but is only geographical.

Thanks for great tools!
