Long story short, I got a couple Apple Music playlists I want offline copies of. How hard is that to do?

If I can get them on Spotify, I know of a couple Spotify scrapers that would let me download them... I think. I've done albums and I've done songs. I've never thrown a whole ass playlist at it (we're talking 500 songs... each).

I'm not gonna stop paying for Apple Music, but offline/archival is nice.
