Unfortunately, there are technical limitations here. M3U playlists are lists of files + paths, so they’re not really an appropriate way to export TIDAL content.
Export To Excel could work, but unfortunately, like many parts of Roon (Radio, Focus, Discover), our Excel export feature is built around content in your library, so right now it’s not possible for it to export information about TIDAL tracks that aren’t in your library.
TIDAL tracks that are in your library will be included in Excel exports, but TIDAL tracks that aren’t in your library will not. This means playlists imported from TIDAL aren’t going to work at the moment.
I understand the motivation here guys, so I would encourage you to open a feature request so we can track interest in this change. For now, I wanted to be clear this isn’t an easy fix we’re refusing to implement – it’s just a big piece of work that we might take under consideration if there was sufficient interest.
Two other clarifications:
If the content in this playlist came from a playlist you created in TIDAL, it’s going to be referencing content on TIDAL, not content in your library.
This is a subtle-but-important distinction that I explained in a little more detail here. If you’re unclear @longtail007 let me know.
Soundiiz can be used to import or export playlists from TIDAL (and many other services) but it doesn’t currently work with Roon directly.
Sorry I don’t have better answers here folks – just know we are seeing this feedback and thinking of ways to improve Roon.
