I did the same thing, but when I found I could buy the same songs via Amazon and a few other places already in mp3 format with the option to save them where I wanted the first time, I deleted iTunes.

You can do that on Windows OS but not on iOS.

For managing my iPod I used an aftermarket iTunes substitute that allowed more flexibility. I don't remember what it was called, because my iPod died years ago and I got a digital Walkman. It uses a drag and drop method in Windows File Explorer which to me is much easier. Plus the Walkman sounds better (it has EQ options) and they don't even make iPods anymore.
