Comment on: Show HN: What was the world listening to? Music charts, 20 countries (1940–2025)

It's pretty cool! I cross "validated" with the charts of where I'm from and the results seem to be fairly accurate.One question/request: How did you get the data, and would it be possible to filter by language or genre?TBH I'm actually trying to chase which songs were popular when I was a kid - for example I distinctly remember Astronomia (Tony Iggy) being massive in the club/party "scene" (and even in malls I think!) - but these charts only give what everyone was listening to - so they're pop songs in the local language.
