On Green Day's latest CD there's a song (yeah, not specific but can update this once the CD makes it onto rotation in the stacker in the cage) where if you replaced the lyrics in the chorus to the lyrics from Church On Sunday from their Warning CD, it'd be a perfect fit (thanks to the recycled guitar riff). Linkin Park's offering for Transformers 2 is pretty close to What I've Done. Replace the lyrics for the chorus and it'd be a perfect fit. The bass line for Ice Ice Baby by Vanilla Ice was quite clearly ripped from one of Queen's songs. Have you got any you can add to the list?
