ORACION AND THE SECRET MUSIC ITEM...MAYBE...

Well, this is a request page for a game I'm making called Oracion. Me and my team mate, BlobOfGoo, are working on a slightly-religious game known as Oracion, where you play as a few kids who get between the war of heaven vs. hell, after getting trapped by bandits and fall into an inter-dimensional dungeon leading to the Heavenly Yard and Hellish Yard.
My request here is for something I call a Secret Jukebox. Basically, according to where you are, whether it be a puzzle you have to finish, a secret area that will only allow you in at a random time, ect. I need songs, not just songs that I like, but songs that the people who may play the game like. How this is done is you request an artist, tell me your 4 songs, and the category. These are the categories:
Hell

Heaven

Water

Air

Seven Sins

Dimenion

Yes, strange categories...I guess -_- Well, the artist you choose may have songs that can fit into all, some, or none of these categories, but you people who choose the songs can tell which category they fall in, and no matter what, I'll credit you in the game even if the song is a bad choice. Also, you can tell me if you want to be credited or not, for choosing the songs. If you have questions, as I know I may of been confusing to some, then please, ask away! No harm done because of a question!
So come and request songs for the game! I hope you enjoyed this :3
