It's really unbelievable how this kind of melodies can influence one's mood and have such a mesmerising effect. I think the whole soundtrack of the trilogy was and still is a wonderful masterpiece of contemporary music. Not only does the recording boast very meaningful and splendid songs, but the ambient/atmosphere sounds behind play a considerable role too. Every character and situation is endowed with its specific tones. There is also a great diversity in all of that: joy, jubilation, mournful occasions, strife, battle and evil vibes. The LOTR soundtrack has it all, really!
