Chester and Mike explained how they worked on HT in Kerrang 2008:
"Shinoda would first work with Delson on the music before he and Bennington would write lyrics.[...] The producer told them he didn’t like any of their songs. [...] Well, actually he liked two – Points Of Authority and With You,” says Bennington. “We basically had to write a new record in two months. We stayed at Mike’s house around the clock and wrote that album.”
But there were further – and far more serious – problems ahead. Bennington claims he was told he "the star" and that Linkin Park should be his band. Shinoda would be relegated to just being the keyboard player or, worse, jettisoned. Bennington resisted immediately: “I said, ‘Fuck you guys. Are you serious? I’ve only just got into the band, and you’re telling me to start a coup against the guy who writes all the music? It’s <i>his</i> band. If he could sing, I wouldn’t have a job. You fucking idiots, what’s wrong with you?’
Also, Chester did write the chorus of In The End a lot before joining Linkin Park as a poem. Both Mike and Chester revised it and added rap parts for the final version.
