Let's see -- a soundtrack for two icky companies getting together for a marriage made in Las Vegas...
Like all good playlists, there has to be a conceptual development of sorts, in this case moving from the idealism of young love through to realism/cynicism and then on to mature acceptance of the inevitable fate -- whatever that is.
Among the Clouds - John Williams
What a Wonderful World - preferably Maceo Parker

Note that this playlist should, in most cities, be long enough for a trip of about eight blocks.
