Or maybe the could've sounded worse? It's really impossible to know unless we ever hear what these versions sound like. Same for NLOTH or anything else where this is often brought up. The questions are intriguing, but AB might be the only album where we have a solid comparison for early versions vs. the final product. And even then, I'm always prefering the later ones. For other situations, sure, maybe the clip of Magnificent being created sounded different and cool, but what did it sound like with lyrics over it? Was there even a 'completed' version of that or whatever?
Speculation is why we're here of course (haha), but for all the times we think something might be better, I'd say there's also a good chance of it being the other way around too.
