Music in TWENTY FOUR preview - trailer music?

Dear Sountrack-fans,

In every episode of 24 there is a preview of what happened in the last episode.
But especially in season 4, in the last episodes, there is always music used in the preview AND ONLY IN THE PREVIEW, NEVER IN THE series itself.
Is that trailer music , too? Or is it from Sean Callery?
It is not on the Soundtrack of 24, also not on the new one.

I have created audio samples.
Please go to this address:

http://esnips.com/web/preview244thseason

There you will find four tracks.
It is all the same music, always the same track.
But because there are voices in the background because it is the preview of an episode, I have audio samples from more episodes so that you can choose in which it is listenable best.

I look forward to oyur answer.

Thanks.
