Live in a house, there are some Mexican polka aficionados driving their low-riders down the street (I live in Texas) but it only reaches inside as base. Even if Amazon could have found the music they play by matching the rhythm, it does not look like a smart decision to target Spanish ads on this basis. Other than Prime Video, which I don't use quite often, I subscribe to Audible and Kindle, with perhaps 1000 of titles between these two. None in Spanish.

Spotify has the same issue (they play ads in podcasts despite paying for subscription) but I don't know if their ads are just local ads made in Spanish only (I live in Texas) since I have no clue what they advertise. They also play ads in what I believe is Canadian French because it does not sound quite like French (which I also don't know but can understand a bit better than Spanish).
