Coldplay - talk, 2005

"The band received permission from the electronic music German band Kraftwerk to use the main riff from their song "Computer Love", from its 1981 studio album Computer World, for "Talk", replacing Kraftwerk's synthesizers with guitars. In a track-by-track interview given by the band on X&Y, bassist Guy Berryman reported that in response to the band's request, Kraftwerk founding member Ralf Hütter "said something like, 'Yes, you can use it, and thank you very much for asking my permission, unlike that bastard Jay-Z'" (a reference to the latter's "(Always Be My) Sunshine", which uses a Kraftwerk sample). Martin also recalled in a 2007 article in Q magazine the process of requesting permission to use the melody: He sent a letter through the lawyers of the respective parties and several weeks later received an envelope containing a handwritten reply that simply said "yes". That riff was originally written by former Kraftwerk member Karl Bartos."
