Someone found that it seems similar to Xyxyz - Echolands. Yeah, I didn't know that song before. How I made this? One day, I played my piano. That day, I really want to make a song. Then I played in "B A G F# E, B A G F# A" and I edited that to this song. Echolands have the different key, notes and speed compared to this song. So, hope you'll not misunderstand that. But, I appologize if you said I'm copying his song. That's "not".
