Video Game BGM

I'm in the process of making my first video game called ZIN (description in the sig). A couple days ago, I started working on bgm for the game, and while its a lot of fun, its also quite challenging since I don't have much of a sense of rhythym. The first prototype bgm I made is kinda hard for me to have an opinion on. Some parts I like, other parts I don't like. Well its a work in progress so I guess that's to be expected.


Here's a sample of what I made.: BGM Prototype 1

Let me know what you think on a scale of 1-10

That aside, what's your favorite bgm? What makes a good bgm?
