Mercedes Benz Winter 2004 Dream Event

Anyone know who or what the name is to the music piece playing during this commercial. Its a Silver/Metallic Mercedes on snow covered road?

I have been to Mercedes website and there is nothing there, at least yet with regard to the commercial. There is mention of the Winter Dream event but not the corresponding commercial.

I curse you Mercedes Benz!
I now have now this piece on constant replay in my head and I can't get rid of it. I have been known to listen to the THX introduction on my stereo over and over and over.....and over again.

Thanks In Advance.

If you have not already found out, but the name of that tune in the commercial is Beautiful Dreamer. I called Mercedes Benz to find out.
