After itunes 11 update, my music is getting continually corrupted.

Question

So the other day, I updated Itunes to 11.0.2 on Win7. After rebooting, I open iTunes and for some reason, it wanted to scan my entire computer for 'music files' as if I had no library (lies). I let it do it's thing since I had no other option and it found my music plus a whole bunch of crap from a couple of games. Spent the rest of the day deleting these stupid 5 second sound bites out of my library and went to go back to listen to my music. Play the first song and, bam, corrupted; skipped three times in the song and then to the next and so on. After restarting the program, I discovered that pretty much everything in my 'library' was corrupted. I went through with Mp3val and fixed most songs and thought my troubles were over. Turned on my computer today to find my favorite album by Jackson Browne was missing its cover art and the songs, corrupted. A lot of music I have was from my parents's collection and I can't just take a weekend and fly halfway across the country to get them to reload the files. I almost want to say that when the first song plays and is corrupted, I think the corruption spreads to other files that were not affected but play after it.
I have seen several others, while searching google for similar stories and solutions, state that iTunes can pretty much screw its self up. I am currently scanning my computer for any maleware/virus that might have any chance of causing this but I want to say that this is an iTunes issue as it has never happened before.
Other things I think I should mention:
OS: win7
Processor: AMD FX 64x
GFX: Radeon 6870 with Catalyst 13.1
- I recently installed SimCity so who knows if that is having an effect.
- Graphical slider in the player that shows the song's progress no longer updates and only does so when I pause the song.
- Song information at the bottom of the screen states '1 of 237 albums, 0 seconds, zero KB' for every song played
- Been having the usual Silverlight 5 problems with Netflix (again doesn't seem related but who knows)
The only proper solution I can think of is completly wiping itunes off my PC (registry, uninstall, etc.) and try again. The only issue with that is that I feel that itunes will scan again and just further corrupt my songs so I am against that.
Also as I was writing this I went back to one of my fixed albums using mp3val (as a test to see if it was still corrupted) and as I finished reviewing and proofing, it played a corrupted song. Same thing happened where the rest of the songs after it were corrupted but up to the song everything played fine. I played the album on Windows Media player and one of the songs shows sings of corruption. I left the desk for a second due to cat, came back and the next song was playing fine instead of acting up like itunes and skipping through the other songs after the first one. After listening to the album again to find the song, I can't find the specific file becuase none of them show signs of corruption that I previously heard.
My ultimate decision is quickly coming to just stop using itunes and move on to WMP now that it doesn't suck.  I would love to know if anyone out there has a solution so I don't have to convert my whole library back to a standard mp3 instead of this m4a corrupting format.
Thank you in advance for your help.

Obviously, the songs did not sync properly to the iPad.
Try deleting the songs and then sync them back again. You can delete them by unsyncing them, which would entail unchecking the songs, playlists, albums, etc. in iTunes and follow that with a sync, or you might be able to delete them directly from the iPad by swiping across the songs in the songs tab of the music app from right to left to get the red delete button.
