I know this does not make me look good - but I am a YouTube Premium subscriber. I had Spotify, but they jacked up their family plan rate, and it was only a few bucks cheaper than Premium, then I got the ad-free (without adblockers). I mostly did it to help my kids avoid the toxic ads that are littered into the kid content. The main reason I stick with some of this stuff is for the discovery. Pandora was great, Spotify is ok.
Regardless - the smart playlists, and AI stuff on YouTube music is AWFUL. I cannot put into words how bad it is. Spotify got it right about 1/4-1/2 of the time. YouTube, maybe 1/100. Constantly recommending a country, which I cannot stand. When it isn't doing country, it recommends hard rock/metal which I also do not listen to. I feel like I need a new way to find music, then I could sever ties with all these trashy subscriptions.
I have started buying vinyl with the digital downloads when I find a great album. I feel better doing it this way. Most of my music is not super big name artists.
