Girl Talk - Night Ripper (album)
Notable moments of genius: the last 25 seconds of Hold Up, where samples of Murphy Lee's Hold Up suddenly get sideswiped and taken over by a chopped up sample of the guitar solo from Weezer's Say It Ain't So; Minute By Minute, which features samples from Ying Yang Twins' Badd melting into the opening countdown from Neutral Milk Hotel's Holland, 1945; the second half of Smash Your Head, where Funkmaster Flex samples are layered over a distorted version of Elton John's ballad Tiny Dancer; Bounce That, rocking hip-hop samples over the guitar riff from LCD Soundsystem's Daft Punk Is Playing At My House; and finally the beginning of Peak Out, a mix of Eminem, 2 Live Crew, and Pavement's Cut Your Hair!
