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."

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

La Chona is like a national anthem

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.
