1960s-1970s
Bohemian Rhapsody -- Queen
Break On Through -- The Doors
Crosstown Traffic -- Jimi Hendrix
So far, only Lasso, Bohemian Rhapsody (which will be fun tiemz with harmonies and keyboard) and Been Caught Stealing on both games. Lasso isn't even certain, since ther has been no comfirmation of the artist. However, a few repeats from the older Guitar Hero games.
Also, JUANES OMG YES I LOVE JUANES Seriously, I'd but RB3 just for that song (and Bohemian Rhapsody keyboard).
Rainbow In The Dark is on RB3, so I'm hoping for a Dio song on GH: WoR.
And, finally, seeing how 'Here I Go Again' is on RB3, we can safely assume that 'Still Of The Night' will be on GH: WoR. :D
