Four days ago the musical group "Cañada de la Cumbia" posted a tribute to Dragon Ball Z and the video is spreading like wildfire -- over 3.2 million views at the time of this posting.
Despite my last name I've spent most of my life in the US, so I actually had to look up the difference between Salsa and Cumbia (I primarily listen to bleeps and bloops) and double check that they're not part-Canadian (duh), but rather from Cañada in Oaxaca, Mexico. Today I also learned that "Gringas," as pictured in the now-famous Goku Taqueria, refers to a type of soft taco in a flour tortilla stuffed with steak, cheese, onions, and coriander. Hungry yet? The music video appears to have first been popularized by OhDios, a Spanish comedy site.
Anyway, the video is a hit but La Cumbia de Goku is not without critics, and as expected most of the YouTube comments have little to do with the video. Many are hating on Mexicans in general: The comments are riddled hecklers descending from every Latin American country poking fun at them colloquialisms and modest production values, including Mexican-on-Mexican hate speech. Pretty depressing stuff.
I can't say I'm a fan, but I'm happy for their success. They'll surely be treated like Gods at local anime and gaming festivals. I wouldn't be surprised if this becomes the new Haruhi dance down South.
