It's better to treat your maps as works of art. I get a lot of my map ideas from the music I listen to. I'd literally listen to the music as I'm mapping. It helps me create things that induce some sort of mood in my maps.
Vindicta Diaboli came from In Sorte Diaboli by Dimmu Borgir, and Necro Forest Remastered was influenced by Blood On Ice by Bathory.
Music is awesome.
