Wasn't it already released like a month ago? Or was I misinformed?

@Ravenlight: This site tends not to get these kinds of things wrong, although I haven't been on RB in a month so I wouldn't know for sure.

It's out today. And I made an updated video. And Brad's now singing (as he should be).
 
  

Just bought this when I saw it was available. Currently ranked 3rd on Guitar despite only have 99% (ahead of 5 100%s, shame on you :P). Stupid choke near the end cost me the FC. I'll go back to it and FC it once I can be bothered and get that 1st place ;).

Awesome to finally get to play this, a great song. Thank you so much Ozone for everything you've done for this.

Can't get RBN songs in australia major bummer

Found me the bomb - Rank 1st in the world / drums expert. For you giantbomb... for you!

@xxDrAiNxx: and for Gary.
