This popped into my head earlier tonight. So I threw it together in a few minutes. It sounds ungodly familiar so it may be something I've heard before/something that already exists but I figured I'd upload it anyway. FUN STUFF! Have a listen and lemme know if you know why it sounds familiar to me.
Also, it's just a small loop... I looped it 3 times so it's not TOO short if you actually like listening to it.
