Sirus_me, are you crazy or what ? The recommendation not to sing those was to ensure that crowd don't bored. Have you ever been to proper concert ? You should be the who should get life, I am all right. If you insist on singining those songs go on but don't go around using vulgarities to show your immaturity.

And don't get too personal here, if you don't like to here what you don't like then I suggest you don't post anything on any forum, including sajha.
