Upgraded to iTunes 11 and iOS7. Now music syncs incorrectly.

Question

Yesterday I updated iTunes on my Windows 7 desktop to version 11.1.0.126 and iOS 7.0 on both my iPhone 4 and also my wife's.  When I was done I had thought the process had gone perfectly, infact I was and still am very impressed by how easy the task was particularily considering how many changes there are.  However, what did not go so well was the syncing of our music.  My wife and I listen to very different types of music and I do not necessarily want her Robin Thicke mixing with my Metallica, (or vice-versa).  And having used iTunes and iDevices going way back, I am very proficient of using the features within iTunes to keep our music and playlists seperate.  But after completing my update I discovered that while all of my music was infact on the device I also had many random songs and artists from our music library that I don't particularly want showing up when I hit 'shuffle'.  For example, there are now a bunch of songs by Frank Sinatra and the Andrew Sisters of my iPhone that we downloaded from the iTunes Store to play at my grandmothers funeral.  When looking at my iPhone's music tab within iTunes you can see thay all the artists that I want synced have boxes with checkmarks in them, as they should.  But you can go through the songs on the iPhone while looking down the list in iTunes and see many artists on the iPhone even though the checkboxes in the iTunes music tab are empty, including artists, albums, and playlists.  I have taken two steps I took to troubleshoot my problem.  First was to check the box of a particular artist that I didn't want on my iPhone (yet it was), and sync, and then uncheck the box and sync again. The second step I took was to remove all of the music from the iPhone and one-by-one go through the lists rechecking boxes of the artists whose music I wanted synced to my iPhone.  On this attempt, when I unchecked 'Sync Music' box under my iPhones music tab in iTunes, it removed all of my music and said there were zero songs on my iPhone.  However launching the music app on the phone showed that all of the music that I wanted on my iPhone, and whose boxes I checked were infact gone.  But all of the music that was thrown on randomly, such as my grandmother's funeral music was still on my iPhone.  The data gauge at the bottom of the iPhone's summary tab even showed the data being taken up by this audio even though the music tab claimed there were zero songs.  And of course when I synced the music that I actually did want on my iPhone back, it all transferred fine, but the random unwanted music is also still there.  The same issue happened with my wife's iPhone 4 but in reverese, meaning that all of the music with a checkbox that is checked in the music tab in iTunes transfered correctly, however so did a random sampling of music that she does not want.  I have double checked that 'Automatically fill free space with songs' is turned off.  I assume my next option would be to restore an iPhone to it's factory defaults and try from scratch, but I'm wondering if the issue lies elsewhere seeing as the problem occured with both my iPhone and my wife's.  I thought it might be wise ask for a little advice before trying that option.
I'll finish by saying that this is a minimal issue to me in relation to my warm feelings about the look and changes of not just the new iOS but of all the Apple products that I have ever owned.  My roots go deep into the Apple ecosystem.  These are all astonding innovations.

diesel vdub, i use 11.1.1
solved the issue today. first sync with itunes, so all the stiff you bought on the mobile will be backuped.
1. uncheck sync music in itunes and sync. all the music will be erased from mobile device
2. check music player on the mobile device. just the unwanted songs will still be there
3. go on the iphone to settings, general, usage, music player. there is just a few mb from the remaining unwanted songs. swipeleft and erase the content. switch iphone off and on again
4. repeat step 2. there will be no data. otherwise repeat step 3
5. check sync music in itunes and sync. all the music will be back again but not the unwanted songs.
