I haven't notice that playlsit before. It has some good music. My opinion is that, when it comes to music streaming across the board, there isn't enough time dedicated to classic music. Which is one to the reason why I wish more old school bloggers use Spoitfy, and help curate some of this stuff.
To be honest, you're better of just keep lstening, and use Spotify radio. This is very important, because it allows Spotify to collect more of your listening habits, so that their algorithms more accurately guess the kind of music you're interested in.
