On October 24, 2000, Linkin Park released their debut album, Hybrid Theory, through Warner Bros. Records. Bennington and Shinoda wrote the lyrics to Hybrid Theory based on some early material. Shinoda characterized the lyrics as interpretations of universal feelings, emotions, and experiences, and as "everyday emotions you talk about and think about. " Bennington later described the songwriting experience to Rolling Stone magazine in early 2002, "It's easy to fall into that thing – 'poor, poor me', that's where songs like 'Crawling' come from: I can't take myself. But that song is about taking responsibility for your actions. I don't say 'you' at any point. It's about how I'm the reason that I feel this way. There's something inside me that pulls me down. " Bennington primarily served as Linkin Park's lead vocalist, but occasionally shared the role with Shinoda. All Music Guide described Bennington's vocals as "higher-pitched" and "emotional", in contrast to Shinoda's hip-hop-style delivery. Both members also worked together to write lyrics for the band's songs.
