What is the best service for legit new/unknown music discovery. A decade or so ago, I remember listening to a podcast that claimer Pandora used 100+ data points in a song to analyse and provide recommendations.

Was that ever true? And if so, a decade on I don’t feel any services I know do that. I feel like if I listen to something from Adult Contemporary (or any other category), they just give me the top 300 songs from that, in some random, made up list.

I’m not saying Spotify is bad, it’s just nothing rarely surprises me.

Who has the best recommendations for new, unheard, non-popular music that is actually like the song you are listening to?
