You are out of your head. Being a muslim you do not know your own relegion. Shame on you. First ask the maulana or your city Mufti as to what is the meaning of this song & why muslims should not sing it.
Singing this song is idol worship. Anyone who does idol worship has done "shirk" & Allah doesn ot pardon such people. So 1st get your basics right about your relegion before making a bold statement that you will sing this song.
May Allah bless us all with the right knowledge that help us all in this world & the hereafter.
