In their defense, the first two are essentially the same album (only 1 or 2 different songs). One is an import, the other is a U.S. release.
I haven't heard the new album yet, but I read that it's a different mix of 'Jerk it Out.'
I agree with HomesickAlien that 'Jerk it Out,' - while catchy as hell - isn't even the best song on 39 Minutes.
