The badn that's REALLY being ripped off wholesale is Faith No More. While AiC had a heavy sound, they're songs were interstingly structured. FNM was a funk metal band and that exact sound, down to the exact tom sounds on the drums, is being ripped off.
There's a band called Papa Roach, if you close your eyes, you hear FNM...there are plenty of other bands that sound just like FNM. I'd sue for damages. THe state of pop music isn't.
The musical guest on each of the last two Saturday Night Lives have both been reeeeally "reminiscent" of FNM. I might have missed a week, but I'm pretty sure it was the last two episodes.
