Mighty Like Us by Kevin MacLeod
Only 6 monophonic synths and a drum set in this entire, extremely peppy, undeniably enthusiastic, off-kilter, oddly satisfying electronic piece! Even at that, it gets pretty dense near the end.
Try this one! You'll like it! (you'll probably like it... figure about 90 percent guaranteed to like this piece by the end.) The uncompressed download comes with a mix done using electronic drums. It has a very different and more machine-like feel. Chances you'll like that one are lower... but it is totally usable for a harsher feel. You can download this in uncompressed format here. Download comes with individual tracks so you can make your own mixes.
