Malmquist bias[0] for neighborhood music!
It would be hard to find that correlation because you can’t get a base rate. I don’t think you can measure the distance, so you don’t know if it’s loud or close. Maybe there’s no correlation independent of the music taste of the neighborhood.
Lots of Spanish doesn’t surprise me. It’s a neighborhood that’s still largely Mexican, and Latin Pop is really big in the US in general.
Malmsteen bias?
