I mean, just play the soundtrack of Conan the Barbarian by Basil Poledouris on the background. If you get bored of it in less than 7000 hours, there’s something wrong with you.
Then again, for me, background music is just that - background music. As long as it’s not out-of-place, I barely register it after a while. It simply enhances the overall mood of the setting, but I pay no great attention to the music itself.
