Seeking Non-Synching Itunes Alternative for Iphone

Having sincerely tried to use the late versions of iTunes to simply add or remove songs for my iPhone4, and fed up with lengthy unwanted synching operations, I am looking for a simple alternative, a program like old, old iTunes where I can just drag and drop stuff from/to an iPhone from my Mac.

So much unwanted crap music had somehow found its way on to my iPhone that I decided recently just to erase everything and start over. After the initial success of directly removing all songs, I opened iTunes (12.1), selected an audiobook that I did want, nothing else, and hit synch. Then I looked on my iPhone and two additional songs had suddenly appeared (one of them, appropriately titled "I Feel Possessed" by Tim and Neil Finn. So I give up...you win, Steve even if you are dead. I just want to be able to simply and manually control what is on my iPhone (like I could back in the early iPod days).

Any software that will do this?
