Yes, I agree!
I listen to all types of music, and my main "brand" is rock/hard rock/metal. I really enjoy most, especially Judas Priest, Iron Maiden, Y&T, AC/DC, and some of the lesser knowns - Saxon, Krokus,Tesla...and the list could go on forever...
I think that the lines get blurred and we try too hard to categorize bands. I have approximately 2000 pieces of music (CD's and LP's), and it would take days to get a list of the good works.
It would certainly be a walk down memory lane!!!
