I'm not a fan of Nelly Furtado, but I always had respect for the fact that her music seemed to be more intelligent than most other songs on the charts at the time. But "Promiscuous Girl"? From the album "Loose"? WTF? I read the lyrics to that song and it is poorly written. (If you like the song, that's your choice, and I hope you enjoy it, no disrespect intended.) I just think it sounds skanky.
BTW if you're a very promiscuous girl, having sex with many, many men, you will get, er... 'loose'. Lol.
