I am father of a singer. She has been singing for fourteen years continuously. Many of the music directors assured her work but no way came forward. I have examples of many. Last assurance I got from Anu Malik in a public show. But that too of no avail. Any way. do not disturb yourself by all these. You practice to the best of your ability. God will definitely help. They are the people who are assuring are of no use. They assure to come in public eyes. Rest you will know better. This field is very disturbing. Please do not get disturbed.
