I think that Rock Band should have...

More eves?
Also, Master Exploder from "The pick of Destiny".

ha master exploder would be fun to sing. and i wish the guitar hero 3 had ended with the song against the devil like in pick of destiny.

I DO NOT NEED! oh wait I guess I do need the mic :D.

I would certainly buy a Tenacious D dlc if they ever do that. I have always been a fan of theirs. Good music and hilarious lyrics. Gotta love the D!!

The Cure...they always had awesome bass parts along with guitar...and drums too. :)

The D would be the best DLC possibly available for Rock Band. The guitar and singing would be amazing!!!!!!
