"What I've Done" (2007)
For their third album, Minutes to Midnight, Linkin Park teamed with legendary producer Rick Rubin, who helped them move beyond their nu-metal roots. Lead single "What I've Done" summed up the band's new approach, shifting the focus to Bennington's vocals rather than the interplay between his soaring voice and Mike Shinoda's rhymes. Moving from vulnerability to desperation, the singer explores regret above an ominous, hypnotic piano riff. "We're straying away from a lot of the predictable sounds we've had in the past," Bennington said in an interview with MTV upon the single's release.
