Hi, 
zickerr, and welcome! I'm one of the Downers who's very interested in Tolkien-related music and has done some research on the use of music in the books as well as listening to compositions inspired by JRRT's works. 
I just recently started a thread introducing the LotR Symphony by Johan de Meij, which was composed in the 80s, well before the movies were made. It's wonderful music! More information and a link 
here.
Several Downers have written on the topic, and we have a sub-forum dedicated to the book 
Music in Middle-earth here.
I'll post more for you when I have time to look deeper into the forum...
