When Linkin Park play live they are known to do some cross overs, like recently they've been doing so with Bleed It Out, but previous they've done it with Points of Authority. I've created my own Points of Authority cross over, and it actually occurs twice in the song, at the start and at the end. The first rap verse in Wretches & Kings can be heard from 00:00 all the way to 00:35, and then the second verse rap can be heard from 03:12 to 03:42. You can listen and download here. Let me know what you think. Update: I've done the same thing with Points of Authority / 99 Problems / One Step Closer. The first Wretches & Kings rap verse starts at 00:15 to 00:45. Then the second rap verse kicks off at 02:45 and ends at 03:17. You can listen to download it here.
I only listened to the first one, to be honest the looped beat was pretty irritating, and I'm sure there are Points instrumentals floating around somewhere. Other than that, pretty decent stuff.
