I'm sure other streaming services have the same and curators can pick from a much larger set of music, from any part of the world. More than they ever could at a radio station where they had to order and ship CDs around.
There's also many independent internet radio stations or music podcasts these days which can be launched for little money, don't require a broadcasting license and can be listened to from any place in the world.
I understand the nostalgia angle, but objectively it seems like what we currently have is better and more open on all counts.
I have a list of "Shows" I follow, with regular updates from star guests (Tim Reaper for jungle music [1] , Lena Raine for video game OST [2], ...)
Their "NTS Guide to..." [3] is really great to peek into a new genre as well.
I highly recommend.
