I am really loving your loops. It's not often I listen to a barely-over-a-minute-long loop for long at all, let alone over 10 - 20 minutes. Great job! There's really a lot of heart and energy in this music. It is not a simple game loop like many of the ones I have seen here. Some serious retro effort was put into this and I appreciate that.
I think I'm going to favorite you now :)
