Just today andrew showed me a few videos on youtube and they were amazing. They are quite long so you don't have to watch the whole thing. (P.S. you will probably go into Aww while watching Video2)
First he showed me this one. It's someone who took different techno songs from games and anime and linked them together acually sounding good. You only need to watch 3:00 minutes of this one.
Then watch this. It's the same music, but someone made a custom mario stage and put them together. This is called an Automatic mario stage because you dont do anything but start the stage and because in the game some blocks and stuff will atomatticly move you, you don't do anything. Make shur to pay attention to both the music and mario sounds. Stop whenever you want, but I doupt you dare will.
Oh, and on the the description of the second one, it hase the order of the songs.
(P.S. yes I know a few of the songs)
