I think it's a good thing this collaboration that Linkin Park has make to produce a album with mix up songs, you know. I happy to know Linkin Park could collaborate with rappers Like Jay-z and it's could be possible that Linkin Park collaborate with someone else maybe not make a album,but make 2 or 3 songs with another artist. I less appreciate on Collision Course that the fact the album contient only 6 songs, but for the rest it's a excellent album, you know. They had put a lot of efforts on this album for the fans...
