What am I supposed to do? I grew up listening to pop music and to this day the "niggunim" play in my head and out of the blue I will start singing them. I even have stored away the theme songs to various TV shows and movies. [I sing Rocky's "Eye of the Tiger" before I participate in a big boxing match. I am in the "Feather-she-bi-featherweight" division].
So here is the question - If I [or you] am chazzan in shul, may I [or you] use these tunes for davening??
Here is a summary and discussion of the various views on the topic. It is interesting that what for the Tzitz Eliezer is a "chas vi-shalom", for the Yabia Omer is a "no problem - even the great ones did it".
