Even as I hear the song looping over and over it has enough of a subtle change to it that it doesn't seem like it's just a repetitive sound. I feel that it fits really nicely together, it's not really busy and it is very smooth on the run through while still being up beat and electric. I would suggest that you worked the loop better at the end, it is loud and going strong then just drops back to the soft beginning. Really great work.
Please contact me if you would like to use this in a project. We can discuss the details.
