It's funny because the kind of setting you describe would be absolutely wonderful to me (I mean, it can't literally always be nighttime and raining, right? It just seems that way in popular media...)

I'd recommend William Gibson's Bridge Trilogy -- Virtual Light, Idoru and All Tomorrow's Parties. They're largely set in sunny California (mostly San Fran) and while things are a little weird and shook up, the setting is overall not that different from the world as we know it.
