A rather obvous choice, Elvenpath by Nightwish. Oh well. I heard it after the movies, though I'm sure it was released first. The song has a good deal of Finnish stuff and Beauty and the Beast mythos and other "fantasy" stuff, but there are real Tolkien-y parts. And Bilbo gets mentioned. 
 
I'm not a real metal fan, but I like the song anyway. And I think NW has done a good deal of Tolkien-y songs.

 That bit has an almost Smith of Wooton Major feel.
