Wow, I guess nobody has heard any of these songs or disagrees that they are 'popular'. Where are all the music critics here?

i've heard "Hey Ya"...that's it.

i listen to almost no radio and just bits & pieces of mtv/vh1...so i hear almost no new music at the pop level.

Hey Ya! - love it. I suspect that most people aren't listening to the lyric, btw, but just like the groove.

The Scientist - as good as most of Coldplay's stuff. Nice, not groundbreaking.

White Flag - I don't know why I like Dido so much, but I like it.

Here Without You - I don't think it is their best song, but I note that my wife has bought exactly one song at the iTMS after hearing the band play on Jimmy Kimmel Live - this one.

Beautiful - disagree on Xtina. It was this song that I heard without realizing who it was that made me realize that she is a great singer. Good song, great voice. Too bad about the skank ho stuff.

I am ashamed to admit that I haven't yet heard the Alicia Keys song, though I liked her first album.

And don't worry about the nickelback songs. They're alright, but nothing super-special.

I have no idea what the lyrics to Hey Ya! might be. But my ass is moving just thinking about that song.

Love both Outkasts equally - freakish blends of '70s funk, soul and contemporary hip-hop.

Love Coldplay, but somewhat less than their last album. Same with Dido.

The rest is of the Great Pool of Blah, nothing I would notice one way or another. I must veer from Phillip's charity toward Xtina, however. I was so scarred by accidentally seeing the video of this song that I still flinch when I enter a room with a TV in it. Surely, she can sing to the extent that she can hit notes and project and whatnot, but her aesthetic choices in what she does with that voice render her a living self-parody. And then there's the skanky ho stuff.
