The soundtrack for Sir Peter Jackson's highly anticipated The Hobbit movies will be released next month, and features a track by Neil Finn.
The Hobbit: An Unexpected Journey Original Motion Picture Soundtrack will be released on December 11.
It will be available both digitally and as a two CD set.
The original score is by Academy Award winner Howard Shore, who wrote the music for the Lord of the Rings trilogy.
It was recorded at London's Abbey Road studios by the London Philharmonic Orchestra.
Crowded House frontman Finn's contribution is an original song entitled Song of the Lonely Mountain, which he wrote and performed.
The OneRing.Net website reports the song will be used during the end credits of the first of the three Hobbit movies, also called The Hobbit: An Unexpected Journey.
Shore won three Academy Awards for his music for the Lord of the Rings films, two for Best Original Score, and one for Best Original Song.
"I have looked forward to returning to the imaginative world of Middle-earth for quite a while," he said.
"I read all of the books by Tolkien, including The Hobbit, when I was in my twenties, and his deep love of nature and all things green resonates deeply with me."
The first Hobbit movie will have its world premiere in Wellington on November 28 and is released in Australia on Boxing Day.
