Lyrics with infinite meaning (Hopelandic)

In 2002, the band Sigur Ros, with their highly anticipated album "( )" - yes, the album title is *parentheses* - was released. Upon release, all tracks on the album were untitled, though the band later published song names on their website. All of the lyrics on ( ) are sung in Vonlenska, also known as Hopelandic, a constructed language of nonsense syllables which resembles the phonology of the Icelandic language. It has also been said that the listener is supposed to interpret their own meanings of the lyrics, which can then be written in the blank pages in the album booklet.

Here, the line between voice and instrument is blurred almost completely. Listen to the "lyrics" in the song below.
