Sharing a track from Tidal will take you to a page that links to the song on multiple platforms. Try this: https://tidal.com/track/68705949?u

That doesn't help for whole playlists, but it at least helps with sharing with friends

I've been using Syncthing for this purpose. My notes are synced between a desktop, laptop, Android phone, and Android tablet. It took me forever to finally take the time to try Syncthing, and it's been nearly flawless.

Sounds like you're talking about the readable line length setting. That's an option you can turn off in the default settings of the app.
