Alter Bridge is better than most band names out there. Audioslave isn't that original of a name. Linkin Park sounds retarded. Hoobastank, huh? Alter Bridge is as original as Submersed.
It's funny that they decided to change their name and to lowercase the letter D in their name. They probably didn't want to be labeled in the nu-metal category. SubmurseD sounds and looks nu-metalish to me.
