Hello there! Let me clarify something before starting the thread:
I'm not a fan of Bruno Mars, never liked his songs, however at late 2012 there was a certain new single from him that reminded me of my favorite band of all time. (if you know the song, you know what I'm talking about)
So yeah, this certain song called "Locked Out Of Heaven" has everything Rock Band 3 can offer: Guitar, Bass, Drums, lots of Keys and fun harmonies.
HMX have released some Bruno Mars songs before, so it would be very weird not seeing this one released for RB3. Check out the song if you don't know it yet by clicking here.
Anyone interested to play it?
