I just listened to the whole track for the fourth time. I've now come to the conclusion that it is bookended by truly beautiful melodies, but is otherwise quite useless. The only reason to repeat the same sounds for 7 hours on end is just so you can say you recorded a 24-hour song.
Someone said there's no flac of this, it was an mp3 only release. Not true - it was released with 3 files/formats: 320 MP3, 16 bit WAV, and 24 bit WAV.
I like the track a lot. But I'm a fan of drone/ambient/experimental.
