Well... my only predictions by now are (based on the last DLCs):
Train - Drive By
Heart and Soul - Huey Lewis & the News
You Make My Dreams - Hall & Oates
Take Me Home Tonight - Eddie Money
Sorry, I do not expect to see Muse in this. I'd be pleasantly surprised, but I don't see it happening.
What I do see, though, is a few more indie rock songs thrown in. I'd love to see Los Campesinos! in this setlist, especially "You! Me! Dancing!"
If P!nk and Shinedown can make it in, Three Days Grace might, but I hope Men At Work does with Be Good Johnny.
Hmm, let's go with:
Avenged Sevenfold - A Little Piece of Heaven
Coldplay - Violet Hill
Dead or Alive - You Spin Me Right Round
Dire Straits - Money For Nothing
Eddie Money - Take Me Home Tonight
Fleetwood Mac - The Chain
Linkin Park - New Divide
Paramore - Decode
Red Hot Chili Peppers - Can't Stop
The Zombies - Time of the Season
Remember when Rock Band 3 consisted entirely of songs withheld from DLC packs?
Yeah yeah, but if two of the worst 2012 DLC artists with holes in their packs can get songs, I have faith in others as well.
This just confirms Elton John, Collective Soul, and Barenaked Ladies packs.
Lets go prediction machine:
The Police - Demolition Man
Scissor Sisters - I don't feel like dancing
Men At Work - Be Good Johnny (for something different)
Daft Punk - Digital Love
Public Enemy & Anthrax - Bring the Noise
The Killers - Somebody Told Me
Asia - Heat of the moment
The Who - The Seeker
Dr.Dre & Ice Cube - Natural Born Killaz
