It's a new album supposedly on Ebay. Also there is another 3 disc set that has 55 songs and all the demos of the songs on hybrid theory. It also has the songs from the hybrid theory EP. Is this a joke? It even has some old remixes.
I already asked around about that a while ago, and it's been on ebay for a while. According to what I've heard, Erection is a bunch of songs by other people that have been mistaken for Linkin Park, and the 2nd Erection disc is Meteora. The other 55-song discs are stupid and fake.
