Gracenote is owned by private equity and has limited availability of data. I prefer to encourage the use of more open data. MusicBrainz or Discogs would have been better choices than Wikidata based on quantity of entries. Though in 5 minutes I have been unable to find if Discogs even has external IDs, and I am not sure of the quantity of Spotify IDs that MusicBrainz has.
Great that you want to use open sources, but now, you've just provided more evidence for my case as you've listed 2 new "sources of truth". Even that fact that there are plural truth sources indicates no one source is truth. Why are they different? Same reasons that have already been discussed
So, we really have not made any forward progress here
If If If. This isn't blind pessimism. This is from someone that has dealt with metadata from studios/labels for just under two decades. IMDB was meant to do this for movies/tv, but yet it's an absolute dumpster fire.
So from an outside perspective, it's fun to dream a little dream, but from a gray beard it's just yet another dream.
