"Well, when I’m singing I’m a completely different person. I could be very free, depending on the situation I could do what I want. I would have to deliver, like with many songs, a lot of emotion if a song is very sad, as with a very happy and excited song. It depends, it depends. Compared to when I’m my normal self, like whomever, of the public." — Selena Quintanilla Pérez.
