Is blasphemous Music ok?

Immediately post-college I dated a woman whose mom was born again. She considered The Grateful Dead to be "devil music". So yes, emphatically!

This all reminds me of attending Black Flag concert In Pontiac Mi sometime in 80's, same night Pope speaking at Silverdome. I recall thinking how ironic adherents passing the blasphemous adorned with  spiiked mohawks, tats, body jewelry, leather on the streets of Pontiac Mi. on this one particular night in this one particular place, and I get to experience it!

I think that the OP should give us a definition of what would constitute "blasphemous" music.

i look to Ted Nugent for nuggets of spiritual guidance….. I would adopt a self proclaimed world traveler, but i ran out of pages..in like my 6th passport….

I believe that the Catholic Church has been found to act in a manner infinitely more blasphemous than could be accomplished by the spoken word....
