Insert old man yells at cloud joke. But seriously, if a band that sounds like another band winning a Grammy is your yardstick for music culture losing all sense of integrity, then I dunno what to tell you. "The biz" has never been about "deep artistic integrity" it's been about moving a product. A band sounding like another band isn't a lack of integrity, it's just a group of people who liked that sound, said "I want to do that"... and then did. So what? I mean, is that not what all musicians do? You hear some sound, it moves you, you think "man, wouldn't it be great to do this"... and then you go do it? If you really want "artistic integrity" there's mountains of underground music out there, and it's not that hard to find.
