Collision Course

Collision Course is a CD/DVD set released on November 30, 2004 by rapper Jay-Z and rock band Linkin Park. It went to #1 on the Billboard 200 upon its release. As of August 2009, it has sold 1,934,000 copies in the United States alone. It has sold more than 5 million copies worldwide. Due to its short time length 21:18 with six tracks in total included on the disc, the release has been identified as an EP. All of the tracks included are mashups combining songs by both artists.
The DVD contains behind-the-scenes new footage of the making of the album, as well as the second take of all of the Collision Course songs at The Roxy Theatre on July 18, 2004. Also included are the five scenes from the concert shown on MTV Ultimate Mash-Ups and a picture gallery.
The first single released from the EP, "Numb/Encore", achieved great airplay on the charts, and stayed on 6 months after its release. "Points of Authority/99 Problems/One Step Closer" was also released to the radio in the US, but was never featured on the Billboard Charts - the videos for both that track and "Jigga What/Faint" were also seen on Kerrang! TV in the UK. "Izzo/In the End" was also heavily promoted on the official Linkin Park websites.
It is the second EP ever (after Alice in Chains' Jar of Flies in 1994) to top the Billboard 200, going on to sell over 300,000 copies in its first week.
