This is a nice little application that isn't much different from several other nice little iTunes-interface apps. As with almost all of these apps this one lacks a customizable list of display options: in particular iTunes (like most others) will not show Composer instead of (or as well as) Artist. Are there no programmers who listen to classical music? Aside from this (and some non-standard interface choices, as others have pointed out, that are still quite clear) there's nothing particular wrong with iTuner, but I also don't see any particular advantage over some of the other options.
