It is a beautiful and melodious song. It really gets the best out of Beyonce's voice, it challenges her voice, but she still comes out as a strong and talented singer. I love the variations in the song,as they ensure that the song doesn't become boring.

I bought this simply for Ring The Alarm Freemason's Edit Mix,,could care less about the title track,,,

This song is more of a Destinys Child first album song. This didn't sound well coming out of a grown woman at all. I hate it.

yes. I like this song and i listen to it quite often. But this song is so stupid. No one is irreplaceable. I don't care if your a famous singer, famous actor, doctor or lawyer, and average joe, or a loser. It's hard to find a new boyfriend/girlfriend or lover. She sings about finding a new lover in the next minute. Her songs lack substance except for independent woman and survivor. Even though she's a better dancer she's no Madonna. There is only one Queen of Pop and that is Madonna. And yes. Madonna is still very successful. Even though Madonna's Confessions on a Dance Floor flopped in the US, her albums are selling like crazy in other countries like Europe. Her tours are always solded out too. I guess countries have better taste than the US. Because the only thing Americans listen to is stupid hip hop and fake singing singers like Nicole Richie, Paris Hilton, Ashlee Simpson. I hear Halley Berry is releasing an album. Give me a break.
