Weird And Oddly Specific Playlists

My wife teaches Bilingual middle schoolers (spanish/english). Around 40% of the kid's Moms are from Mexico.

To get the kids to clean up the classroom she has a small list of school appropriate "Cleaning songs". She never announces it or tells them to clean up. She just turns the music on 5 minutes before class ends.

All the kids with Mexican moms, pop up and start frantically cleaning. The other kids, after a bit of confusion, follow.

She says "I might as well take advantage of all the Pavlovian training their mothers have done."

La Chona is like a national anthem

Good playlist but its missing all the ballads. If it doesnt sound like a late 90s/ mid 2000s KLVE radio then my moms not having it

Where's "rata de dos patas?"

Not Hispanic or a mom, but I've been wanting more Latin-american music in my life. Will have to check it out.

On a side note: does anyone know of any Latin-american metal bands? Like, kind of a fusion of Latin-american stuff and metal?

Edit: thanks y'all for the suggestions! I've been sick so I haven't really been able to check anything out, but I'll be sure to do so when I feel better.
