Some songs won't play

I have been trying to play random playlists from my whole library and occasionally I will run into a song which cannot play. It just gets stuck, but choosing the next song will work.
The MP3's are from a variety of source and seem to work normally. Is there some sort of know issue with certain types of MP3 files, large databases, folder structures, naming or anything like that which could be causing this sort of problem?
