I will probably end up replacing some songs from TW3 OST on second playthrough. I know, its heresy.
Would be cool if the horse had a custom radio station xD.
In conversation with one composer, we discussed how to make fast travel to be less important thing in videogames and make horses play more major role in gameplay. And we both agreed that music plays an important role in such matter. And each place & situation must have their own track for a horseback riding. But it would take more time and resources, though. It is taking a lot of time and resources.
