 Soundtracks for "The Hobbit" have been released in an extended, two-disc form, offering over two hours of music each and liner notes by Doug Adams.The music is, for the most part, presented as it is in the film and by the film order, but some pieces were re-edited to augment the listening experience into something more akin of a concert program.The recording is nevertheless incomplete, especially given alternate music used in some of the film scenes, although fans have since unearthed much of it and a rarities CD is attached to the upcoming book.
