On TIDAL’s web interface there’s a section called MyMusic where you can flag records or artists for quick access. This is a good way to store stuff you might want to listen to later. Why can’t we access this list when we use TIDAL through Roon?
When you click the star to favourite an artist, album, track or playlist in Tidal, it becomes available in My Music. When Roon syncs with Tidal these favourited items will show up in Roon. Also, any Tidal item you “Add to Library” in Roon will show up in My Music in Tidal (after the next sync).
So, to answer your question, those items will be in Roon. They are also available in the Tidal View in Roon, under Your Favorites.
