Who cares, just talk. I dunno, I love NIN, and I'm only a bit of a Lostprophets fan, but it's probably a bad move on his part. He'll likely be out of a job after the next tour.
I dunno, I don't really care. It's not like he's burned his bridges in Lostprophets. Just an experience (and money) thing, most likely. Besides, it's Nine Inch fucking Nails. You don't have to like them, but they're one of the biggest bands in rock. And he's only 20, man! Experience of a lifetime. He also said if Trent was willing to do it, he could most likely play The Perfect Drug.
He seriously thinks he can play that song? Omg I fucking hope so, I hope they can get it down by SOundwave XD
