punctuation of any kind in the song, commas(,)Periods(.)apostrophes(') etc. etc. etc. It will cause it to give you the old "You already have a song with that title" routine... 

     I find it happens all the time to me...  I am always using names like "When's the dog coming home with my paper", and "When you're hot, I'm not, and when You're cool, I'm still a fool for you"... things like that.... so I have real problems..
