GTA V for IV LoadingScreens - As far as I know, this is the first mod with a loading screen like in GTA 5. I can't say that GTA 5 loads the same way as in the mod, because. I don't have a console.
*Please note that the music will remain the same (from GTA 4, because it is superimposed on the video). But I'm working on it and soon, maybe, I'll make a mod with loading sound from GTA 5.*
