Bio Hazard Battle(called 'Crying' in Japan) is a game made a while ago in 1992 for the Sega Mega Drive. I played it a lot in my childhood, and it's one of my favorite titles and also one of the games with my favorite game music. 
It's a side-scrolling shooter, and to describe it in one word would be 'creepy'. The game's backstory is about a far planet where, after multiple Bio-Hazard Wars, the planet became completely polluted, and the last surviving humans inhabiting the planet took shelter in a space station. Now, quite some time later, you have to travel out to the surface with your so-called 'bio-ship' to see if the world is ready to be rehabilitated by humans, encountering strange mutated creatures everywhere. 
 The music is very... non-standard for a Mega Drive game.  I don't know how to describe it really,(exept the word creepy or dark does come in mind for the music as well )  but the 8 tracks of the game can be found on YouTube.

So... Maybe, if somebody has time and would like to give this a go, then that would be amazing . 
I'd love to hear your toughts, even if you don't want to remix it .
