Files Being Generated In My Library.

I got this new problem, I've been getting a lot of problems (Mainly this one http://getsatisfaction.com/songbird/t... if someone could PLEASE help it's been days and no response.)
Anyways I think my new problem is from the last.fm add on update, I no longer have my radio stop every 3-5 songs but what I have found happening a bunch of files in my library for no reason.
They show up as blank but I rescanned metadata and this is what showed.
