Syncing Local Files to Android

[triestenapoli]

I've been doing a lot of online searching for help on this topic but nothing has been effective. I'm attempting to sync the local files from I put into Windows Spotify to my Android app. I'm on the same network on both devices, signed out and back in, updated the apps, allowed Spotify through the firewall, set network to private, ensured the tracks are mp3, downloaded the playlist, etc. Nothing works. Any help would be appreciated.
