So as people have suggested already there’s deemix if you’re happy to pay for a Premium subscription. If you want something somewhat more automated there are scripts that can be used with Lidarr to automatically download new releases from deemix.
Of course there’s also yt-dl to download from YouTube but the sound quality won’t match that of Deezer.
For Android there are apps such as Innertune, SimpMusic or ViMusic which let you stream and download from YouTube Music. There’s also Spotiflyer which I believe downloads tracks from YouTube again but links with a Spotify account for playlists etc.
For both Desktop and Android there’s also SpotTube which uses a Spotfy library and streams from YouTube Music.
