it's WAY too similar to Hollaback Girl for me. my boyfriend's mom listens to KissFM in the kitchen and we were in the living room the other night playing with the cats and that song came on, i had to go into the kitchen and listen a little closer because i could have sworn it was a remix of Hollaback Girl hahaha!
it is a pretty catchy song though...but so was Hollaback Girl, so i guess..if it works for Gwen, rip it off and make it work for you too! the beat in the beginning with the background vocals is HIGHLY remeniscent of Missy Elliott's stuff, too. but again, it worked for her, so why shouldn't it work for Fergie?
anyway, most of BEP's beats are blatantly ripped off, so Fergie probably doesn't know any better
i'm not trying to trash BEP, i liked Elephunk (i dunno if it was for BEP or for the guest appreance by Papa Roach..but i did like it haha)
