I've found Spotify's new music algorithm goes - "Oh, you used to listen to Motorhead and AC/DC? I think you'll like Kiss and Def Leppard"
YT music algorithm goes " Well I think, combining that with all the other stuff you listen to, you'll like Shaka Ponk, Deluxe, Pretty Reckless etc etc"
Google is a cunt these days but the quality of suggestions is vastly superior
