Heh, if you want to associate Emo and NIN together, listen to "With Teeth". I have the same regard to that CD as I do towards FOOS - They're both shit. Other than that, all the previous NIN CDs have been excellent. "Year Zero", while I am a fan of the theme, is just a little too techno for me.
The tour for "With Teeth" was badass. I think Reznor realized "With Teeth" wasn't that great and performed 90% old songs.
Na man, i'm just fooling around, i really like most of what NIN recorded, and do not consider them emo at all, tho, like i said, some of their songs have emo'ish lyrics. But then again, so do many of the other bands i listen to, so meh.
The whole "Year Zero" album was made in response to the shitty trends in music, especially emo crap. And while the lyrics may seem similar to the untrained eye, their underlying ideas are completely different than those of emo music, no?
