Are you people serious?? 'Girlfriend' is the worst song I've ever heard out of Avril Lavigne, which isn't really a feat because none of her music is really very good. But I think this is a new low. I kind of liked "I'm With You", but this song is so unoriginal, trendy and annoying. Someone should kick her in the mouth and ask her what she was thinking.
People need to stop copying each other. It's like a couple songs come out that are somewhat successful and have this "new" sound (ex: fergie, gwen stefanis new sound), so then everyone does the exact same thing. It was only new once, and I'm sick of hearing this junk.
I don't think it will do well on the radio. Maybe on TRL and teenybopper stations, but not on regular top 40 stations.
