The video starts off with two kids a boy and a girl—both are speaking Spanish. They wake up and find that not only are their parents gone but also everyone in their town, so they pack up and try to find people.
I know there's a scene where they destroy a car.
When they're traveling they come across a big furry Totoro-like monster in a cave, and the monster is cool. Then it shows us that there's a bunch of kids and they're all running around having a blast and there's also a bunch of other alien looking monsters, but they must be good 'cause they're not attacking anyone.
And that's all I really remember. I've looked everywhere for it and if you can help it would be awesome.
I watched the video 5 or 6 years ago at least. I don't remember any females singing; I'm pretty sure it was a band of guys. It wasn't heavy metal or anything; it was more like pop. I don't remember much about the actual sound of it to be honest.
