This song was made by the group Sweet Lemon (i'm keyboardist)
It's in spanish and at the first part that loud sound IS an error at the end there is a sound radio-like of a commercial at first it was an error but it was funny so we decided to leave it like that and now its not an error.

Esta cancion fue echa por el grupo Sweet Lemon (io soi tecladista)
Al principio de la cancion el sonido agudo es un error y al final de la cancion se oie algo como un comercial de radio ese no es un error.
