iTunes - Many Songs with Errors

[SamAshleyBlogs]

Out of no where today A LOT of my songs in iTunes have exclamation points next to them and will not play. I got the new rMBP on the day it was released and transferred songs over then. At that point, I went through my library and tried to delete duplicates.

I realize this could be part of the issue, but I only deleted DUPLICATES, not ALL the songs on an album. Now, I have quite a few full albums that won't play at all. No idea what happened. I did upgrade iTunes/OSX recently, but I feel like this can't be the issue.

Or is it?

The exclamation mark indicates that iTunes cannot find the media file for that song. This can happen, for example, if you have music stored on an external drive that is not mounted at the time you launch iTunes. Make sure your music files are in the same path that iTunes expects them to be. How, exactly, did you transfer the music to the new MBP?
