"Secret" MIDI files in Windows

go to C:\Windows\Media and play the file called onestop. At first it sounds like Kirby, then Sonic, then...I don't even know. It's like if Dream Theater made midi music. It goes all over the place.

My face when I listened to the track for the first time:


There are other cool songs in the folder called Town and Flourish. I don't like those as much, but they're still kinda cool.
