I’m a nerd about music metadata and it drives me nuts to see incorrect release dates on streaming albums. I don’t care about when an album was re-released – when I’m looking at an artist’s discography, I want to see the year the album originally came out. Plus, a lot of times MOG or Spotify get track titles or artists slightly wrong (usually because of poor tagging by whoever submitted the album). Sure, you can manually submit corrections, but what about allowing users to correct data. If changes get voted down, the information reverts back to the original data.
Of course, it’d be nice if the streaming services could automatically get original release dates from AllMusic or Discogs, too. Combine that with user-editable data and I’d be a happy man.
