As a former Apple employee, I can testify to what Mike S. is saying...and then some.*
Since the passing of Steve Jobs, Apple does not give a **** about music lovers, OR about the opinions of their customers in general.
I'm an Applehead, meaning I became enamored with Apple technology several years ago when I received my first Apple product (a first gen iPod Touch) as a gift. I quickly poured thousands of dollar into Apple technology, replacing my Windows computers with Apple products (iMac, MacBook Air, iPad, iPhone, Apple TV, etc).
Then I got the chance to go to work at Apple; you'd have thought I'd be ecstatic, right? I was...for about the first three months. Then I started realizing that, with the passing of Steve Jobs, everything was changing at the core of Apple. In a personal interview shortly before he stepped down as CEO of Apple, Steve Jobs noted that the success of "his" ideas was simply that he listened to people; he took note of what people were saying, what people were imagining out loud, what features and functionality people were asking for in other products, and he made that happen. He gave the customers what they were asking for well ahead of anyone else, because he paid attention to what people wanted. That's no longer the case; now, the best that Apple can do is try to take what Steve Jobs foresaw, and make cosmetic changes to it. (When is the last REAL noticeable change/improvement in the iPhone? How about iOS? And the MacBook? Quieter fans, faster processor...How original!)
My whole point is that, yes, I strongly suggest that everyone who is frustrated with the loss of artwork in iTunes 11 (I was forced to upgrade to 11 when I worked at Apple, but refuse to install it on my own systems here at home) to go to http://www.apple.com/feedback and voice your opinion. It will let them know what people are angry about, and in spite of the fact that they no longer care about the individual wants, they DO still care about the almighty dollar. Enough angry voices MIGHT eventually get their attention
Again, I hate to see what is happening at Apple, but sadly, the handwriting is on the wall. It's not that there are no more "genius" minds like Steve Jobs; it's simply that no one at the helm cares to listen to you anymore.
You—and I—deserve better.
