is there a song by Wisin & Yandel (could be somebody else, I merely over heard it) that says something similar to:

"tan simple, tan sencilla, asi de perfecta eres"

any help will be greatly appreciated

thank you all!!!

thanks, but I don't think that's the one
this one says: "perfecta, inigualable"
and then almost at the end, says: "perfecta, sencilla..."
