Latino dance song, help?

Well, this is a song I've heard yesterday, unfortunately I haven't rememberd a single word, heh. But I'll try to explain it more:

It's a female singing it, the song is fairly well known, I'm sure I've heard it before, so it's not a new song, it might be a couple of years old, maybe even more. I'm pretty sure the whole song is in spanish.
The chorus unfortunately goes eh-eh-eh-eh-eh-eh-eh eh-eh-eh-eh-eh-eh-eh, so that's not much of a help, hah. It's kind of a latino dance song, altough you might say it's techno aswell.

I'm sure someone would remember it if they heard the tune, but I hope it's possible to find it this way... Any help would be appreciated =)

Anyone?
