I'm saying it's not art. Well, I guess it was Francis Scott Key's art, but it's not Steve Tyler's art, or anyone else's art. The song is to glorify the nation, not the singer. You're right I'm not an artist so maybe I don't "get it"; all I know is when I hear someone (not necessarily Tyler) scratching & mixing their own rendition of the anthem, it pisses me off.Wow!
You have a lot to learn about art.
EDIT: Thought of another way to express what I'm trying to say: The flag of the U.S. has 50 white stars on a blue background, with 7 red stripes and 6 white ones. Now, imagine if "artists" were to start changing up the colors. If they flew a flag with alternating pink & purple stripes at half time, wouldn't that be a desecration of the flag? Well, when people take personal liberties with the anthem, it's the same thing in my eyes; they are desecrating it. There's only one way to sew the flag and only one way to sing the anthem. Maybe we've forgotten that since we've been letting people sing it however they please for a long time.
