Got the iPod, what the crap is up with iTunes?

[SomethingClever]

So I picked up the iPod on Friday, and I'm having a hell of a time with iTunes.

Here's the situation. I had about 2,500 songs organized into folders by genre and subfolders by either artist or album.

I dragged them all into iTunes and they're just random in there.

So I tried creating "playlists" with the same names as my folders and subfolder, but it looks like I have to re-drag and drop all the files in them. Plus, it doesn't alert me if I make a dupe... which I could easily do with so many files to sort (I won't be able to do all of 'em at once).

Anyone use iTunes and have some tips on how to make this easier?

Thanks...
