iTunes has always been Apple's playground for trying out new UI, if they want to see how the public react to something new that doesn't relate specifically to another product, iTunes is generally where they'll try it. It got the blue monochrome sidebar before Lion, it got Cover Flow first, and it's had it's UI played with more than the rest of the system. They seem to figure that if it works in iTunes, it'll work in the rest of the system, but at the same time, people who use iTunes know it well enough that if they change stuff people will still be able to make it work.
They've been working on a new slider, for example, (see the volume slider) and I wouldn't be surprised that after a iteration or two we start seeing it crop up elsewhere.
