If anyone doesn’t want to write their own software, Lidarr has auto import from lists. You can add your playlists from Spotify and last.FM and it will watch them and automatically download the songs from the lists. There is no Tidal, or Deezer option though which feels like a ball drop by the Lidarr devs.
I have two in my main UPS for over 2 years without issue. Just make sure to buy them with built in BMS so it manages the battery for you.
