I remember reading in the Butch Walker autobiography that these guys got bummed out of a lot of royalties by their label and publishing company so the fact that they can't afford to finance themselves and the families that they all now have is no real surprise :(
I mean, they didn't even write their biggest song... There guys certainly aren't making the big bucks, it's expensive to self release an album. People seem to think if you have a radio hit or two from 2002 You're set for life. Not the case.
