Was radio ever anything other than that, in general? There have always been (and still are) DJ's that host radio programs that do hunt down "what music is best" (fyi, troll - that is an opinion-based issue). Everyone has the right to find that out for themselves and make their own decisions; there has never been a better time for that. There is more diversity than ever on the radio even if it is more corporate-focused, and with the internet and things like SoundCloud there is effectively no barrier for any music to reach any listener in such a context.
If you're willing to look a little bit, you can find all sorts of great music on the radio. I'm in Houston, Texas and I can hear straight-ahead jazz, zydeco, rock and roll, blues, and about 6 different flavors of country. I still haven't found a reliable source for opera or Finnish death folk metal (yeah, it's a thing), but radio is plenty good and worth every penny (it's free).
It helps to have an HD-radio, because I find little gems of stations that otherwise might not have a frequency in regular AM or FM.
I listen to a lot of streamed music (Google Play is my current preferred platform), but there's still a lot of life left in radio. We just need more college and "underground" stations, even though that's not likely to happen with the current administration in Washington, who seem to prefer turning the airwaves over to a handful of giant corporations, who don't know a goddamn thing about music.
In case you want to hear some Finnish death folk metal, here you go. I find it's great music to have on when you're gaming.
