What i would say to this is that,if you consider yourself a Die-Hard Linkin Park fan,then this album may not be all that good.
It doesnt have that single music which you'll always remember,like you would remember "Somewhere i Belong",Or "Numb",Or "Forgotten",to me the one song which does come nearly(if at all) close to this is Bleed it Out.
But in think in this album the same spunk is lacking,they have kinda become another boy band group with more mushiness than the expected rocking beats!
End Verdict: There are A heck load of sites claiming the album to be released and they have a link,also there are quite a few websites with previews ,This is would advise you to check out before you go and buy anything!
