I am surprised at all the mis statements about iTunes in this thread. But let's keep it simple
you want answers to how to organize iTunes on a PC? go to a Mac store and get the correct information.
If you don't like iTunes just delete the application and use media player or any other PC music Player.
Here's some info on how to sync to iTunes.

Don't expect iTunes to display iTunes music files the way a PC displays files. iTunes is a different animal.
If you want to master iTunes use the stores that provide the training.
Happily, when it comes to managing music flexibility & Apple do match.
