Improper use of our National Anthem?

[Gary's Ice Cream]

I was shocked and appalled today to hear a BMW commercial on WBZ (1030 AM)
that used the Star Spangled Banner as its music bed.  The spot appeared to
be a national one tagged at the end by one of the usual WBZ production guys.
I was beside myself that BMW would do this and that CBS would allow it to be
aired.  At one time CBS was known to have the toughest "Standards &
Practices Department" in the business.  If this is any indication then they
must have eliminated that department altogether.  Am I over-reacting or is
this a reprehensible use of our National Anthem?  Your comments are
appreciated and solicited.
