It just seems like they've finally understood what makes a song memorable, as opposed to just playing all the same riffs without any thought for cohesive songwriting. The biggest problem I've always had with JP is that all their shit sounds the same at the end of the day. Try to find samples of the new one perhaps - this is remarkably better/different than before, but it's still got the Jag Panzer trademarks, so don't go in blind if you completely dislike their previous efforts.
