iTunes to work with now

I can't make my own folders. I can't just copy music from my library.  I can't just click on a few songs and hit delete.  Working with this version of iTunes is the absolute WORST of any music manager I have ever used.  My next phone will definitely NOT be an iPhone after this craptastic piece of software. I'll go back to a Samsung I guess.  At least it was easy to manage what was on the phone and wasn't with that one. Now I'm stuck with this junk till my contract runs out.  Talk about non intuitive in the extreme.
