Well, for your first listen, obviously it's most optimal to listen in one sitting. But with projects such as these that have 6 hours and 30 minutes of content, I would suggest looking deeper into every track, every song, and relisten to each song until you get an understanding of what every song means.
There is so much detail. so much sound you can simply skip over or ignore, I with 100% seriousness suggest to the listeners to memorize each song. And obviously that takes way more than multiple sittings, the same way you rewatch a movie multiple times and notice interesting details. So many people skip over post awareness stages, it saddens me, it's my favorite part of the album yet so many people disregard it as simple noise. But the more you listen the more you notice how enjoyable each section is. I, after the first listen listened to each stage on loop for over 4 times, until I got an impression of each song. So, one listen without paying attention is not something to be considered impressive.
