OK cool - thank you for your input.
My only query is on this:
The only suggestion I have at this moment is that works like “A New Day” should be classified as songs, as soundtracks are collections of music attached to some kind of a production (a simple way to think about it is soundtracks collect songs).
I got told off for setting works as Songs with No Lyrics, as apparently a song requires lyrics to be a song (theres another thread somewhere where I don’t think we ever got to the bottom of this).
EDIT - the thread about the above, Work Type for "Instrumental" Music
