For me music has always represented a storyline and trip through time and space. And that is why especially ambient music works so well as a soundtrack for videos, slideshows, movies, or somewhat any kind of presentation.
And that is why I give you two different train journeys.
Ulrich Schnauss - Train Journey from Jackbox on YouTube
Reham - This Thirst from Francois Vogel on YouTube
Second one is maybe not exactly ambient music, and the song is not long enough for my standards (should last over six minutes). But it is a good example on what skillful artist can do with the music.
On Vogel's 360 video make sure you click on it to drag the point of view around. Especially look aback when Reham Khan starts to sing at 1:17.
