currently the ones I've found are fake, they have the new songs already released and just older DCFC songs renamed.
you can watch DCFC's live performance of "You Are a Tourist" on Late Night with Jimmy Fallon here http://www.prefixmag.com/media/death-cab-for-cutie/you-are-a-tourist-live-on-fallon-video/52440/
So far there's only a fake one, which as Shadey said is just the songs that have been released so far plus old songs.
It's streaming here if anyone wants to listen. http://www.npr.org/2011/05/22/136465054/first-listen-death-cab-for-cutie-codes-and-keys edit: just finished listening. good lord. this is up there with Transatlanticism. might even be better (though I'm sure many hardcore Death Cab fans would be completely unwilling to think that).
Holy shit! it's quite good, don't know if it's better than Transatlanticism, gotta take it all in for a couple weeks.
Yeah after listening to it for over a week I'd say the same. There are some standout tracks but overall it didn't exactly blow me away.
