Hey
Zickerr, welcome!
The music... well there is a lot of it made by some famous composers, some theatre-companies, musically (at)tuned Tolkien lovers and the basic Barrow-Downers (not to talk of people on other web-sites - even if they can't beat us...
).
I think you have some pretty intresting threads here to the music of the Arda / music of the Middle Earth as we have a few professionals abroad and quite a many afficionados as well to make it interesting and educating at the same time.
So just delve into the threads and when you don't find what you seek, open a new one for your specific questions / ideas.
