I thought I would share this with you guys. Everything in this song is 100% Pokemon sounds. Even the back beat is. If you really want to hurt your brain try to find all the Pokemon and their sounds in the song. I've known about it for a year and thought I would let the word out about it <3.
EDIT: It seems the youtube link isn't working. Here is a link to the song instead
