If McCreary's 15 themes are on this album. I think the following tracks might be suites.
These are the most obvious
Galadriel
Khazad-Dûm
Nori Brandyfoot
The Stranger
Númenor
Sauron
Valinor
Elrond Half-Elven
Durin IV
Harfoot Life
Browyn And Arondir
Halbrand
Elendil And Isildur
Not sure about these
White Leaves (Maybe a theme for Telperion or the Two Trees Of Valinor)
