Guitar Hero III to get ‘God of War’ DLC?

Tucked away in a recent Playstation Underground news letter was this little advertisement;

That’s it, that’s all… no other information was given so all we can gather from this is that there is going to be a God of War song available (at least for the PS3) on June 5th.

I don’t know what they could offer, some theme music perhaps?  If this is a free download then it will be appreciated.   We’ll keep you updated when we get more information.
