Vanessa Hudgens recently credited singing along to Celine Dion when she was younger for giving her the great vocal range she has.
Some may say that can't be correct, as many people like to sing along to Celine Dion too, perhaps in the shower.
But the difference is in how you do it. To improve your singing, you need to sing along seriously. Sing like you're performing for a crowd. Do it with passion.
Now, the question is, will somebody one day credit singing along to Vanessa Hudgens for their vocal skills?
