I dunno bout mental but heavy metal is a pathogen except for Metalica.
 
	 
 
	Yup, Cream stands alone, and I am also a big Led Zeppelin fan.  Strangely enough I also am into Johnny Cash, Linda Ronstadt, Willy Nelson and I could listen to Jennifer Nettles all night long.  I like singers more than guitar players, but both are gods to me.  As long as it's music and done well, I like it.  Two Cellos, Pistol Annie's, A YouTube group (I think) called Postmodern Jukebox does a cover of "All About That Base" that simply blows my sox off.   Anyway, back to AutoCad issues.
