IMO 6Music is the pinnacle of this concept. I have yet to find a better source of new 'good' music. I try to listen to it as much as possible.

I made a 6 Music 'now playing' app (https://radio-tracker.geoffclayton.com/) so I could easily keep track of things I liked. I kept hearing things then forgetting... I never _quite_ finished it, so never really advertised its existence, but over the course of year it has collected some interesting stats. It's there and it works, anyway! Mainly the Spotify integration part is not quite finished.
