IPhone 5 :: Removing Music From ITunes?

I have an iPhone 5 running IOS 7.1.1 and the current versions of Maverick and iTunesÂ

I am trying to listen to my huge iTunes library in alphabetical order by album. Every week I typically remove a section of albums from my phone (using iTunes) and load up the next batch. I never had any issue with doing this. I manage the music manually and it has always worked. Â

Last night I did the same thing and in the iTunes interface everything looked great, but it was odd because I didn't have a lot of room on the phone. When I looked at the music on my phone, it didn't remove most of the albums I told it to. So, for example, when I look at the music on my phone, "Florence and the Machine" is there and plays. However, it doesn't show up in iTunes when I plug my phone in. Â

Outside of deleting every single song on th ephone one at a time, I'm stuck. No settings have changed and everything worked perfectly until now. How do I get songs off my phone if they don't appear in the itunes interface anymore?!
