@diapause thanks for taking the time to write this great answer - it’s perfect.
I particularly agree with your points around the production itself, but I probably wouldn’t have noticed it without a frame of reference that you’ve now kindly provided - so thanks for that 
Completely agree with the Pink Floyd and ‘rock’ thing - that was me just being lazy - I do appreciate them for the range, experimental meanderings and envelope pushing technology tweaking. Glad my reference wasn’t completed wasted though 
And, thanks for the list - I know about 2% of those acts - so looking forward to discovering some new sounds!
