A few years ago I made a song using the free midi tracks called "4 Chords" which I'm sure everyone has heard of. I came back to it just recently and decided to change the midi files a bit and add a drum beat or two. This was the result. (NOTE: Towards the end, you might hear the "Simple Synth" instrument. I chose to do that to basically make a mashup of the new and old version that I made)
