sorry but I really don't understand this whole once in a lifetime voice thing when it comes to Perrie. Don't get me wrong she has a great voice when she's on form, but I've seen sooo many performances where she is way off key, and I don't think she can hold high notes as well as she thinks she can. The voice cracks happen fairly often. Like I said she can definitely sing but I don't think she's the most amazing vocalist to have ever existed. I much prefer Jades voice
