At a Glance
If you are looking for a player that's heavy on aesthetics and visualization, you might want to look elsewhere. Foobar2000 has a minimalist interface, which you can customize according to how you want to organize and view your media library.
As Foobar2000 notes on its site, this is an "advanced" media player, meaning that it isn't as user-friendly as iTunes. In terms of audio quality, however, it is superior to the ubiquitous player. Download Foobar2000 and learn its basic functions before you begin downloading the optional components.
