The first vers is a perfect build up... The sound is quite tight. The drums are very mechanic and a bit muffled and the sound is almost a bit electronic. Then the second guitar enters and promises that something is gonna happen and keeps the groove going. As a final sparkly touch there is this third guitar that is very high and single notes. And then come the moment that gives me shivers and brings tears to my eyes. All the other instruments than Kelly's voice is cut away as a moment of quiet before the storm, and then booom... the music foldes out and uses the whole spectrum and Kelly is one of those girls that sings like she would die if she didn't on this song. And that gets me. Then on the second verse is a bit more rocked up version of the first one. But the second vocals are added more, that's a really cool effect all through the song that I really like too, almost all of it is done with a double vocal of Kelly, either just similar or with a slight second melody. Makes the sound deeper and fuller. Then for the second chorus that again gives me shivers... and now the bridge that is also great... It just takes of and flyes og and just when it's boring the guitar is cut away for a few beats which makes it interessting, The it quiets down and the the electronica drums form the beginning are back. Before a great build up and just doing all that is possible to make the last vers explode, before ending almost where it started.
The lyrics are of course doing a lot too, since it's a very universal "I wanna get back at you song". I can imagine it would be very good for break-ups and girl power. And I really really believe Kelly when she sings, though I really don't like her as a person after the whole world idol event. I am sure we will get back to that some other time.
And oh... The producer is not surprisingly Max Martin, the pop mad man behind all pop sensations:
he crafted a string of worldwide hits for pop artists like the clean-cut boy bands The Backstreet Boys and *NSYNC, Britney Spears, P!nk, Swedish starlet Robyn and the Swedish eurodance star E-Type among many others, in the mid/late '90s to mid 2000s.Wikipedia
But even though he is knowen as the ultimate teen pop commercialized producer but he is very very good at what he do in that genre and makes a lot of really perfect choices, I think.
More on the song
Just read there about the song being very similar to The Strokes song Last Night.
And that is actually quite true... at least when it comes to the rhythm. Love The Strokes song even more though :)
