The hard part is that some of these songs might be being saved for RB3 but apparently Lego maybe where the songs appear first.
For me DLC that is missing obvious great songs include:
Rush: Spirit of Radio- We know HMX has a ton of their songs I would be shocked if one does not appear. Plus Geddy sounds a bit like Mickey Mouse so he is kid friendly for sure
Fall Out Boy- Dance, Dance- Kid friendly and on the leaked list
Cranberries- Zombie- agree with OP
The Zombies- Time of the Season- agree with OP
Talking Heads- Burning Down the House- great Talking Heads song and great for the game
John Lennon- Instant Karma- I know HMX says no solo Beatles stuff in TBRB, but I would be surprised if they were unable to get a song or two for the other games. I think this Lennon song is a very good family song
Bob Dylan- All Along the Watchtower or Knocking on Heavan's Door. No Bob Dylan DLC yet, you have to know they have something hidden away. Either of these would work and make the parents who have to watch LEGO happy.
