Papercut was released in 2001 as a single. The song is a thesis of someone always looking out for him/herself, and warning others that they are also paranoid.
Even though there are no acoustic instruments in the song, lead guitarist Brad Delson is shown playing an acoustic guitar in the video, and Phoenix is shown playing an acoustic bass guitar. And although there is drumming, Rob Bourdon doesn't play drums at all in the video. Chester Bennington has stated that Papercut is his favourite song from Hybrid Theory. In live performances, the line "something in here's not right today" is changed to "something inside's not right today". Also, Chester screams parts of the first verse during live performances.
On Linkin Park's remix album Reanimation (2002), there is a remix of this song, titled "Ppr:Kut", which was remixed by Cheapshot. Elements from the song were used in the song Sold My Soul To Yo Mama, which appears on the band's 4th annual fan club CD. Furthermore, the mashup EP Collision Course (2004) contains a mix of this song and Jay-Z's "Big Pimpin'".
