What is "tarana-e-pakistan"

Tarana-e-Pakistan is claimed to be the first national anthem that was played in Pakistan's national radio on 14 August 1947 of Pakistan said to be composed by Jagannath Azad at the request of Mohammad Ali Jinnah but this claim is unsubstantiated. It was never officially adopted as Pakistan's national anthem and the Qaumi Tarana was officially adopted as Pakistan's national anthem in 1950.
