The new iTunes sucks and always looses my music. I hate the design and I'm sure you do to. Nobody that I know likes it. If you have iTunes 11 I'm sure you want the layout to be changed also.
iTunes 10.7 had the layout that let you see the album artwork while scrolling, actually worked, and synced correctly with my iPhone and iPad. Tim Cook, the CEO of Apple is leading the company down the hole and he will make it fail. He has done nothing but make their products worse, and charging more for them.
If you sign this petition then I will send this the Apple to show that the public hates the new iTunes and that he should change the design back to the old layout.
