The new songs, and i might play a couple others to try it out. But can't wait to see the rest of the list announced!
The Cure 
My Chem. 
I believe the correct answer here is Freezepop
 More Janes Addiction
 More AFI
[X] More Cheap Trick
 Bloc Party
 Garth Brooks
 Mad Caddies
 Randy Newman
Song of the Century by Green Day - For a good easy start
DLC Wish: More Emperor  Daft Punk  Violent Soho  Madonna  Billy Ray Cyrus  Mercyful Fate  Deadmau5  Asian Kung-Fu Generation  Death 
Probably Foo Fighters just to play some of my regular favorties.
AsianSteev: if you can read this, put more Ska songs on the RBN! Please?
Gamertag: Demitri Theodus
Head Like A Hole by Nine Inch Nails. Unless I feel like singing I don't enjoy that song at all in RB proper. I think it may end up being a blast in RBB, though.
But I believe in this and it's been tested by research: he who  nuns will later join the church.
- Joe Strummer
Since the game takes place in Rock City, and since the city relies upon the note density and so forth to construct itself as you play, there is obviously no more fitting song than We Built This City.
Nevertheless, I think my very first Blitz song will be Show Me What You've Got by Powerman 5000, for an even cheesier reason. There will be hundreds of virginal leaderboards and a whole new set of challenges, and this is THE song with which to storm out of the gate. "Bring it."
