Sound of Sun

Hi Everyone, I am writing from Australia. Most visitors to our site
rent-a-cloud.com are European. We get lots of comments to our video
clips on landscapes in time laps, especially how we use music and sound
effectcs to make them come alive. But for 2 clips comments are very
much divided pro/con. These are "Sun climmbing River" and "Sun Cows".
Question: what sort of music and sound effects would you use for silent
objects like suns, skies and clouds?
Grateful for suggestions.
