The song starts with a nice vibrant intro and the first words have macarena in there... Then it goes on to "tay te te te yette" drum beat, "tay te te tete yette"... Something something "alegria"... Im lost here. Help!

It not macarena, it Magdalena, and the song is Magdalena by Sergio Mendes.

And its in Portuguese, not Spanish. Hope this helps.
