Day/Night Music Themes?

[Hero_Claive]

Not particularly requesting any resources be made, but I was looking around to see if anyone knew of tracklists/buyable assets that feature different versions of certain songs. Huge bonus points if they're day/nighttime themes. I've been dying to incorporate a day/night system into my game, but the one thing holding me back is how so many of my tracks would sound off during nighttime.

Video game OSTs, store assets, music blogs... Anything would be highly appreciated!
