I suspect how you get on with an album like this is probably as much to do with personality as conventional musical preferences. I think if you sometimes like music to take you into yourself it's probably got some legs whereas if music is mostly for taking you out of yourself then it's probably not go that much going for it other than as a bit of a relaxant.
Years ago I went with Mrs Spires to see the Seagram Murals at the Tate, I found myself surprisingly moved by them and was quite happy to just sit there lost in the thoughts and feelings they were evoking. Mrs Spires was "enough now with looking at the red and maroon paint" and we learnt that the best approach if we're going to look at abstract expressionist art (ignoring for a moment whether in this case rothko really is) is that she'll have a quick shufty with me and then head to the cafe and leave me to it. No right or wrong just people who are wired differently.
This album feels a bit like abstract expressionist art to me in that it's really a vehicle to express and explore feelings rather than say anything specific and explicit. That, for those who are inclined to engage with it in that way, those feelings and thoughts will vary from person to person is pretty much the point of 'art' like this. In the same way that colour, line and composition etc are used differently compared to realism this isn't using the sonics to trying to create a set of songs in the conventional sense of the word and it'll yield little viewed in those terms.
Sorry for the poncey interjection but that is basically how I feel about stuff like this.
