Yeah, it's a demo. It wasn't on any album or EP as far as I know.
I downloaded it as being a Linkin Park song on eMule years ago.
Funny thing: if you check the commentaries of some YouTube videos you can actually see people arguing with Trapt (their official account) that this is a Linkin Park song.

We should ask Ryu about this.
+ the hidden track from Shouting Out.
