Are there many Within Temptation songs that have not been released on official platforms?

I want to make sure I've listened to all the songs by Within Temptation 😅

I know that "Gothic Christmas" and the cover of "Running Up That Hill" have not been released on official platforms such as Spotify, Apple Music, YouTube Music, etc., and they are not included on any album

Of course, it would be nice if there was a list of all the songs in chronological order that the band has ever released 😂, but at least it would be good to know the ones that are not officially released on digital platforms
