I don't think that Stone Sour have become too calm on this album. I don't get why people are saying that. It's one song more than CWM , and that song is a ballad. Fail. But I would not say it's soft or anything like that. It still has the heavy moments. In spite of that I think it can't hold the candle up to CWM, just because not one of the 4 (by the way all beautiful) ballads can replace Through Glass and Reborn stays their best song ever.
Their previous albums were great, i heard two of the tracks that were released they sounded very original and the style sounds very aggressive just like 30/30-150.
Corey Taylor said that the album is going to be darker than 'Come What(ever) May', but a lot more melodic, and a lot stronger.
