Yep, I've noticed this issue too. I've tried a few things like re-registering the iTunes COM but it still happens randomly. I find if it 'locks up' (lock up being it doesn't play the song - stuck at 0:00) like this, I can open a similar file in a media player like Media Player Classic and the song starts instantly playing. Is iTunes your default media player for various media extensions? Other than this post, I've not seen anything else about this. You also might wanna consider posting about this issue on Apple's support forums in the iTunes section. They might have an idea too. I've also been pondering if this might be an issue with the mixer on Windows 8 as well, but I'm starting to think it's something else if other media players can 'unlock iTunes'.
Also it's worth noting that when the 'lock up' happens, I notice iTunes' resources spike. I'm going to use Process Hacker to see if I can see what's happening, exactly.
