How to KEEP DELETED SONGS OFF MY IPHONE BUT IT CAN REMAIN IN MY ITUNES LIBRARY?

It's really frustrating because I have over 700 songs and I would delete about 200 and then when I sync my iphone those 200+ songs come back in my iPhone. I want to be able to delete the music from my phone but still have that same song on my macbook in my iTunes. BTW not all my songs are properly organized so I can't just select an album or anything like that… Please Help i really I do not want these songs coming back everytime I sync

I never sync any of my Apple devices to put music on it. Instead my iTunes is set for manual management of music and video. I almost never have problems putting music I want - and only THAT music- on my iPod.

Manual management is just clearly superior in every way and it works on iPods, iPhones and iPads both new and old. I've tried it on first generation nanos, iPod 4, iPad 3 and iPhone 5

You enable manual management by bringing up sidebar in iTunes (ctrl S if you don't have it up already) and clicking on the iPod tab. The main window should show you the main summary for your iPod. The box for the manual management option is at the bottom of the page (it's probably already checked). When you use MM, the only songs that get put on your iPod are the ones you want; the only songs you lose are the songs you don't want anymore.

Every time you update iTunes, you need to reboot your computer.
