Design inconsistency between Mac OS X 10.8 sidebar and iTunes.

I know the general response of the bland, grey icons in Mac OS hasn't been great, and there were some options created to get back the coloured icons after the complaints began to appear. However, I just noticed that iTunes 11 has coloured icons in the sidebar (option+command+s to display sidebar).

Do you think that this is an inconsistency, or might it be a hint that Apple will bring back the coloured sidebar in 10.9?
