Nothing like that I'm afraid. Though I've added m3u links to radio stations and use that for some discovery, alongside bandcamp, reddit, youtube. Personally I find independent radio is underrated, they often save their streams in archives online. Wefunkradio is a good example.

EDIT: incidentally there was a recent Spotify integration component: https://www.foobar2000.org/components/view/foo_spotify , not sure if that still works. It also looks like there was an older one for creating playlists using last.fm.
