I doubt that the Bush comment cost them much at all. I doubt that they have ever enjoyed a better year than 2003.
According to Billboard in 2003:
#3 Top Pop Artis - Duo/Group
#3 Top Billboard 200 Album
#4 Top Billboard 200 Album Artist
#3 Top Internet Album
#1 Top Billboard 200 Album Artist - Duo/Group
#4 Top Hot 100 Singles Artist - Duos/Group
#4 Top Country Artist
#1 Top Country Artist - Group/Duo
#2 Top Country Albums
#2 Top Country Album Artist
#1 Top Country Album Artist - Group/Duo
#3 Top Country Single Sales
sourceThey may have come to a screeching halt, but I'm betting it has more to do with babies than Bush.
