This is the goal:
Yo! RBN Raps
4 Stars on any 3 songs by Alias Unknown, MC Frontalot, and Hyro Da Hero from the Rock Band Network.
But there are only 4 songs for this goal... and only two of which are released for PS3. I can understand this a few months ago, but really? We haven't got the third yet by now? Any news on this or any other songs being released by these artists?
