https://soundcloud.com/nimble76/tango-battle-gen-vpThis has an AABAC format, with a little introduction/ending so as to make it just fine with looping. It has different thematics so as to entertain the listener, not to bore them to the point where they're turning the music down.
You can go with any format you want really, where it be just AB, ABA, hell, A(x)B(x) if you're into that kind of stuff, but you have to keep the listener listening; making a song isn't difficult. making a song that loops isnt difficult. making a song that loops while still being interesting is difficult. You just have to keep trying new styles and methods, as well as new progressions and harmonies. I hope what I've said helps you out. I'm writing something right now that reflects off one of your themes, I'll probably have it done by the end of the day.
