I can’t speak about puerto rico, but in another latin american country i’ve spent a lot of time in it’s very common for every small store to have a loudspeaker and blast (imo shitty) music from 10 to 5. That isn’t even bad compared to the many discos right next to each other than play music as loud as possible to not be dwarfed by their neighbor.

Whenever I’m in a Western city I’m grateful for how much more quiet it is (relatively anyways), even with greater density and size.
