When i was little I randomly came across this video, looking for piano tutorials (since I play piano frquently)
This video has a very special place in my heart, it was the first black midi video I had ever seen and blew my mind, and I also loved the melody, which was in my head for years. I go back to that video and a similar bad apple piano tutorial all the time for nostalgias sake.
oh, and I found out the original song was from touhou through the comments on the video, and I looked up the game and was shocked at how hard the game looked, just like anyone else.
