Please for the love of god, if you're going to pursue Asking Alexandria for Rock Band further please get the new album on here. Stand up and Scream, while being a mediocre album is nothing to the standards of Reckless and Relentless which is much improved and more mature sounding than SUAS.
Songs like Closure, Someone, Somewhere, Morte et Dabo, A Lesson Never Learned and To the Stage are must haves on Rock Band with great harmonies and the best synth work I've ever heard from AA.
So yeah, whoever is authoring Asking Alexandria (Rhythm Authors, is it?) - you know what to do. I know these guys would help out.
