Alternative For Syncing Music & Videos??

[cueball]

I never liked WMP. I store all my music and videos on iTunes. I can't seem to drag and drop iTunes playlists into my media card (Computer> Device> Media Card.)
My main problem with WMP is even though I edit the song/video name, it still syncs over the original file name. If I change the original file name for WMP then I have to rename it for iTunes cause when I go back to iTunes to play the song/video, it says the file is missing. It's a pain!!!

Is there another option so that I don't have to mess with WMP?

Thanks!
