EDIT: AWWW crap. Now I see someone did post this already - feel free to delete mods!
Didn't see this posted so I'll throw it down.
From Kotaku website
"My only main concern with SingStar: Queen was, well, the fact it just made me want to play the songs in Rock Band instead. Something I'll soon be able to do!
A "competitive analysis" chart obtained by Wired - drawn up to show how Harmonix's Rock Band offerings compare to Guitar Hero's - has revealed that along with the two Queen songs included in LEGO Rock Band, there'll be another ten Queen songs coming as downloadable content next month (only one, "Under Pressure", has been named").
That leaves nine chances for one of them to be Princes of the Universe."
