It seems like a pretty good idea. I think there was another couple of bands that have done that also but i can't remember who right now.
It's been so long since I've listened to Limp Bizkit. I have Significant Other and The Chocolate Starfish and the Hot Dog Flavored Water. I liked Break Stuff and Rollin' a lot.
I would say Propaganda for their next single. Although I think priest and channel are good canidates too.
I'm not a huge fan of Limp Bizkit. They have 2 songs that I really like: both versions of 'Rollin'' on CSATHDFW. The only song I have from TUTP1 is 'The Truth', and it isn't that great. Many people have been dissing Limp Bizkit; I agree with most of them, but the thing I respect Fred Durst for is that he helped a lot of good bands get mainstream recognition (e.g Staind and Cold).
