would be mashing up with Jay-Z for a record under MTV's Mash Ups show. The network allowed Jay-Z to choose a group or artist for the mash-up. Jay contacted Shinoda, who began experimenting with mixing the tracks before sending some examples to him. As a result, Jay-Z began working with Shinoda through email. The two decided that instead of combining the existing tracks for the live performance on MTV, they wanted to re-work and re-record parts of the songs to make them fit better. Shinoda explains, "Jay and I realized it's better to re-perform the rap vocals if you're gonna do it to a new beat because the vibe changes and you have to deliver your verse a little differently." Shinoda asked his bandmates to re-record instrumental and vocal tracks as well, and ultimately both parties decided they wanted to release the studio tracks.

A year after the release of Collision Course, Jay-Z was the executive producer on Mike Shinoda's solo effort Fort Minor's The Rising Tied. Also, the song "High Road" from the same record talks about how some critics negatively received Collision Course. Critical reception Collision Course received generally mixed reviews from music critics. David Jeffries of AllMusic praised the album, calling it "awesomely fun". K.B. Tindal of HipHopDX also equally praised the album, saying that the project "will open a passageway for artists who want to dare to be different as well as those who want to work hard to maintain that difference." Steve Juon of RapReviews called the album "an experiment which bodes well since for the most part these two artists each other." Meanwhile, Raymond Fiore of Entertainment Weekly, gave a negative review of the album, saying that the pairing
