Why do we have to have umpteen back and forth convos over “definitive” can we just let it go please. No one wins this argument and who cares truthfully. I assure you this convo won’t change the tags on the site so why bother.
I admit I must have some Pavlovian tendencies. 
Anyway, one could say the same thing about the thread as a whole, as people have raised concerns about the homepage changes since Day 1 yet nothing happens.
I was advised (perhaps in this thread) to not file reports for missing vocalese, etc. tags even I knew one of the options was missing but couldn't understand the differences between the options. Similarly, if one doesn't understand "definitive", ignore the tag and don't use.
Frankly, I consider the definitive recording of a work, if there is one, the most important recording to have on site and so designated. At least top three with first release and first recording. The definitive recording is likely why the work is found in medleys and mashups. It's likely the reason there are as many subsequent covers of the work that there are and will be. It would also be the benchmark to determine "unusual". It's also likely the reason the song and covers are found in films and other pop culture.
To contrast with my position with the vocalese et. al. tags, I never advocated abandoning the concept entirety regardless of my opinion on usefulness, but rather arguing that having three options added high complexity for marginal value, suggesting combining into a single tag as a compromise. There really is no substitute that I can see for "definitive" other than some name change (e.g. "most famous", "most popular", "most well known"). The current "hit" and "more famous" come close, but the definitive recording may not have been a "hit" and there can be several hits and "more famous" of varying genres, arrangements, etc. There simply is no substitute.
