There has been alot of discussing if the Title attribute has any value at all and so far there is no supporting evidence that it helps.
Google has long ignored many forms of spam techniques that worked in the past, prior to, lets say 2001.
Back then it was easy to rank high in search engines by just optimizing your META tags, title attribute, Alt tags, Comments.
All these have been pretty much eliminated in Googles algorithm and play no roll. Imagine if it did. You know how many people would make use of this. I don't think I could count that high. There is no benefit of adding it to your page since it is invaluable to Googles algorithm
